Hesitation and then cutting off - fuel pump?

    I have a 1995 Hijet 5 speed. 28,266 km and got it 3 months ago. It has run great...until now.

    I was out today and it started hesitating as I came out of the clutch and gave it gas in each gear. Then finally as I got up to speed it started spitting and finally I couldn’t get any power at all, engine and oil light came on and I pulled off the side of the road. I waited a few minutes and checked the car, then was able to start it back up and hobble home, with the same event happening two more times on the short trip back. Each time I was able to restart the car and it did ok for a minute until the same issue resurfaced again.

    My first inclination is the fuel pump needs replaced but have any of you experienced this issue?

    Several have had the same or similar issues, with several fix options! First of all, what's the history of the vehicles maintenance? Go to G&R web sight and there are several good tips there! It could be a number of things! If you go into your profile, and click into signature, you can help us, to help you if you put in your vehicle's info, like several of us have done that you see by the bottom, of our post's! The more technical info you put in, the more help, you can receive!

    So, if you take the hose off of the fuel pump, and energize it by turning the key on, does it squirt fuel, into a container?

    Thanks Limestone - I will check out the site tonight.

    It’s tough to know the maintenance history as it was imported this year. The only thing I did after I purchased was change the oil, oil filter, air filter and fuel filter. Have only put ethanol-free gas in the truck since then.

    I will look through my options tonight - sorry that I don’t any history beyond this year.

    Okay, that's a great start! try checking out that line from the fuel pump, and see if you have good, unlimited flow!

    You only need a couple psi. for these little things!

    If that's working properly, check out the newly replaced fuel filter. No knowing the history of buying a used vehicle is pretty common, so don't let that bother you. But many of these things, have had dirty fuel, and or dirty fuel tanks! You might want to, open the drain plug at the bottom of the tank, and drain, a small amount of fuel off the bottom of the tank into a clear glass jar! It will tell you a lot! Let it settle down for a short period of time, and you won't believe what you might find. Dirt, water,(water is heavier than fuel), etc... Most likely it's never been done! These are good starting points! Good Luck!

    Yeah, I understand, tonight when you go in to unwind, you can address your signature. No problem. Maybe, the fuel filter is starting to get clogged, from past owners, with some dirt, or moisture in the tank. Even after you replace the filter, if that's it, it'll run good for a short while, until the new filter starts to get clogged, if that's the problem! That's why it's good to drain it occasionally! Preventative maintenance! Pretty hard to put a price tag on it!

    I've bought 2 Suzuki trucks that were fresh imports and both of them had filthy fuel and coolant systems. I took the tanks off both and dumped them out then flushed them out good with high pressure water and let them drain for a couple of days .After they seemed dry I blew them out with air then rinsed them with WD40 to get any drops remaining. I replaced all the filters and fuel lines and cleaned the carburetors and they ran fine. The stuff that came out of them was amazing, it's a wonder they even tried to run.

    Same here. Imported 2 so far and was amazed that they ran at all off the unusual liquid in the gas tank. Crankcase oil not much better. Changing ALL the fluids right off the bat will thwart a lot of problems.

    I wholeheartedly agree guys! Maintenance, maintenance, and more preventable maintenance! Old school!

    I’ve seen probably 100+ trucks come in. The one thing I’ve noticed is , they are maintained or they are not . Never saw one that “ that antifreeze might need to be changed “ it was “ WTF is that ??? :eek:“ Or Looked like it was changed last week .
    Base line everything , costs less then $100 and you know that’s it’s done and when it was done . Even if you are tight on money , toss a timing belt on it

    Well, in my opinion, good Honest mechanics, have always been hard to come by! Even more so today! Don't get me wrong, there are a lot of experts out there, and any body can use a mechanic in a can, and if it works, and there's no repercussions down the road, well then I'm truly happy for you, but, always beware, because the easy, and cheapest way is not always the best way! Here, were a bunch of friendly poeple just sharing our passion, and advice! It don't mean a thing if you take our advice, like us or whatever! Were just a bunch of friendly guy's giving some free advice to people, and hoping that it helps them! Were not making a dime, were not charging anything, naturally. Were just a bunch of guy's sharing our hobby, and what we like to do to help, out mankind! All we can do is make suggestions, half the time we don't even have all the facts, hence the profile, signature, suggestions at the bottom!

    My trucks tank had the finest grey silt. It would collect on the inlet sock in the tank choking off fuel to the pump.

    I do realize that the so called, inlet sock, is a filter, of some sorts, and it is very much needed. I've just never been a huge fan of that design! It works, don't misunderstand me. Just make it a habit to change it often! That's the problem, verses an inline filter which is much easier to change!

    If it's like mine with the EB engine, there is a carburetor. An old mechanic came by my shop the other day and troubleshooted the unbelievably bad starting (but good running) vehicle. It appeared to be a carb issue, because he worked on the accelerator pump on the carb. I think it has a diaphragm one-way valve or something. Anyway, he worked on that little part and now it starts. But the main reason for the accelerator pump is that it prevents a low fuel situation when you ... accelerate. I think that's your original problem, and it's worth a look. I also had that problem, but I was originally thinking it only happened when the engine was cold and so it just needed to be warmed up... but that's just a cop out for not understanding how the thing works. You need that extra "squirt" of fuel, and if something is gummed up in the pump or it's disabled, you will have bad accelerator response. Take it from a noobie. Or ask a real (old) mechanic about them.

    Unless you have an in tank fuel pump, I prefer one of the glass bodied filters just out of the tank, where you can look at it and change the filter if you need to.

    Older cars had the sock filter so it could catch the rust as your tank went down hill. Cars in those days only lasted 70,000-miles. Now days if you have an out of the tank pump, and put the filter right before it you have the best possible setup. A lot of things on car design tend to be done just because the last guy did it that way.

    Thanks to everyone for the responses on this - I replaced the fuel filter back in Nov when I had the issue and no problems since! I drive the truck every week, but only a few kms hauling stuff around the neighborhood, so oddly enough I'm still on that same tank of gas. I plan to next clean the gas tank, replace fuel lines, and fuel filter again and go from there. Given no issues for last 6 months, dirty fuel and silt had to have been the issue.

    My trucks tank had fine grey dust that would collect on the sock filter in the tank slowly choking fuel supply off. Only happened 1/2 tank or lower I guess filling up stirred it all up into the fuel and it took time to settle out
