Buddys 94 Integra LS dies when you put in throttle

[ChrisR1987]

Hey all. My buddy has a 94 Acura Integra. Today he was running around town doing errends and his car started acting up He described it as bogging down and not running right. And then it completely died on him at an intersection and wouldnt restart. He had it towed home and now he says it’ll start and idle just fine and he can put it into gear no problem but soon as he puts in any throttle the engine quits and he hears a quick but deep, low growling noise coming from the engine. His car has 145k miles. Its a manual transmission with the 1.5L 4 cyl motor. Not sure what block type or anything like that.

He’s thinking its the fuel pump but I disagree because last I checked either a pump works or it doesnt. Im leaning more toward a fuel filter clog or some type of clog or restriction in the fuel system. Tho Im not as familiar to acuras and what makes them tick. So I figure I’d see if I could get opinions from you guys. Any help would be apprecaited.

It does sound like it would be a fuel delivery problem. You are half right about the fuel pump though. Either it pumps or it doesn’t pump is correct, but just cause it pumps doesn’t mean it is providing the correct pressure. There are several reasons that the engine would not be getting correct pressure (laging fuel pump, bad fuel pressure regulator, old fuel filter, maybe the fuel system is being TOLD to provide an incorrect pressure,etc.)Start with the basics by checking the distributor points and rotor, check that the wires are not damaged in any way, check spark plugs for spark,cracks,or build up. Check the air filter. After that you can check the fuel pressure. Remember, don’t assume anything, check everything. If you don’t find anything obvious try getting your codes pulled. Most auto parts stores will do it for free.

My buddy says his air filter is good but he’s gonna check the rest of the stuff tommorow.

here are some videos to help.

Hey guys, my buddy wound up taking his car to the shop. They determined first off there was a miss in Cyl 3 due to a bad spark plug wire, also the distributer itself was bad as well as the shaft connecting the distributer to the engine (not sure of its technical term)so theyre replacing his spark plugs, wires, distributer, and shaft and that should rectify the issue.

Still havnt worked out how to mark the thread as answered

[college man]

thanks for the update. 🙂

Honda’s hardly every have fuel delivery issues in fact NEVER replace a Honda fuel pump unless you’re absolutely sure it’s bad by checking for power delivery and ground at the fuel pump connector itself. I get pretty frustrated at how many people think Honda’s are GM’s and need a fuel pump every time there’s a performance problem. This is SO wrong. I can say without a doubt that the OE Honda pumps are way better than any crap you could replace it with. So don’t go straight for the fuel pump every time there’s a performance problem with a Honda.

As you’ve seen in this thread the problem was ignition related. I only mention this because I die inside a little every time I hear about someone replacing a Honda fuel pump without evidence it’s bad.

That’s interesting to hear about the GM fuel problems. There are a lot of GM engines in the uk with piston failure and it appears to be related to the car running lean. I decided to upgrade mine to a Walbro pump which is noisy as heck but at least I feel a bit more confident on full throttle.

The way you described the car running sluggish then stopping it reminded me of when my dad’s Subaru had a knackered air mass meter, except his car would move off but lurch back and forward. IF id seen ETCG videos id have got the electrical contact cleaner out and saved him a small fortune maybe.

Appreciate the input as always Eric. I had my doubts of it being the pump. To me it sounded like a fuel delivery issue but I was proven wrong tho Im still learning

[EricTheCarGuy]

We’re all learning including me. I just happen to know a thing or 2 about Hondas Integras in particular. I’ve owned 5 of them and I’ve worked on more of them than I can count. Most of the problems I see are because of someone else’s repair attempts. For the most part those are very reliable cars.
