Chevrolet - 1500 :: 1989 Truck Will Start But Not Run For More Than 30 Seconds
May 26, 2012
My truck hasn't run for over a year and no one seems to be able to tell me why. The fuel pump supposedly has 10 lbs of pressure, it has new fuel pump relay, new throttle body, and probably more new things (can't remember exactly). It will start up normally and then it will act like it's not getting fuel and within seconds die. If I keep my foot on the gas and kind of pump it (I know it's EFI) it will try to keep running, but will die, and it really gets rough toward the end like the whole engine's going to fall out. The truck has 300K+ on it but the engine was replaced about 10,000 miles ago. It still has a lot of original equipment.

1991 chevy silverado 1500 4.3 ... Cruising at 55 down highway truck died for 2-3 seconds only to refire itself. After doing so for a few days it wouldn't start at all. Changed fuel pump,fuel filter and all spark plugs. Now runs fine until I shut it off briefly. Then it stalls on me on 3rd,4th and 5th gears. Bucks badly. Is it a fuel issue or something to do with starting it while it's warm. Also it runs good with the check light ON. Soon as it goes off it starts shutting off and refiring itself when I give it gas.

After my truck sits overnight it starts immediately and goes to fast idle for a few seconds, then ithe idle starts dropping until it gets to approx. 400 RPM.If I drive off immediately it will correct itself in a short while, otherwise I need to baby the engine speed until it runs on its own - usually five minutes.I cleaned the MAF and performed a MAF tap test with no success.

What would cause my 1993 silverado 5.0 133K miles, to knock for a few seconds when started. Sounds like the back of the engine area.

1992 WT pick up 263,000 miles had new head gasket installed valves lapped and tune up it was doing it before and does get better when truck warms up, but still can hesitate at times. When cold you have to feather gas pedal to truck accelerating, you can hear truck motor pop through throttle body but will continue to speed up.

Just got a 1990 k1500 with the 4.3 v6 and 5 speed and it backfires. A buddy told me it was shooting flames out of my exhaust. What does that mean?

I have a '96 Chevy Silverado that twice (in about as many months) has had some trouble starting. When I turn the key the engine starts to crank, then there is a loud pop and the engine stops. When I crank it again the engine will start, although more slowly than usual. What could be wrong?

My 1995 chevy c1500 cuts out at idle or the moment the brakes are applied to shift into drive. I replaced the passenger wheel cylinder and bled the brakes and it ran fine for a few hours, then the idle problem stated again. I have check the map senor and a few other electronic component as my mechanic said the problem " might be electrical."

So I used my 2000 silverado 1500 to remove a willow trunk from my yard. 4 Lo, took a bit of work but I tried not to overdo it. Now, truck sputters when accelerating. Once it gets going it's good but the startup is sputtery and bucks a little. What did I do?

My truck just recently started to vibrate like it is going over rumble strips. It only happens over 40MPH and sporadically. It seems to happen when I'm just giving enough gas to maintain speed. Once it starts if I let off the gas or give it more gas it goes away. It reoccurs anywhere from 20 seconds up to a few minutes. I'm afraid my tire is going to fly off or my drive shaft is going to drop. There is no unusual noises or thuds if I go on and off the gas and the universal joints seem tight, and there is no vibrations from on steering wheel.

Several years ago I had to replace the fuel pump - truck had about 100,000 miles. Within the last 4 - 5 months I have replaced the fuel pump twice and just today (about two months since the last replacement), the fuel pump has failed again. That has been the pattern now for the last several months. I have had the work done by one of the reputable car repair shops in town - they have also done work on my 2004 Impala with no issues with the repair. There must be something else going on besides just the fuel pump going bad. What would cause so many fuel pump failures.

I have a 1998 Chevy K1500 4x4 which is experiencing issues on two fronts: brakes and general operation.
For the brakes, over the last couple years, we have replaced just about every part of the system, including - master cylinder - calipers - brake lines. In addition, in the last week, I worked with a local mechanic to bleed the lines and he turned the rotors as well. The result is that while the truck does stop, the pedal height is still really high and feels like there's no pressure until the pedal's nearly to the floor. I get the feeling that if I needed to stop abruptly or at a higher speed than 35mph, I wouldn't be able to. I'm not sure what needs to happen next.
As to the general operation: the first time I start the truck on any given day, it fires up and runs smoothly. If I take it across town, however, and put it in the park, it gasps, sputters, and dies. It is then very difficult to get the vehicle to start again--usually, I have to push the gas pedal all the way to the floor and grind the starter until the engine turns over. After that, I have to keep my foot on the accelerator for 15-30 seconds at around 3000 RPM as the truck shudders and lurches, until it smooths out. Once I put it into drive or reverse, however, it dies, unless I am quick to push the accelerator again. Until recently, the truck had only been driven four times in the last two years or so. So far, I have: - replaced the air filter - added fresh gas (to the old) - added an engine treatment (Sea-Foam) Everything I have done is stuff that needs to be taken care of anyway, and I want to take care of all the little things before I take it to a dealership to have a full diagnostic run on it. I also plan to have an oil change done on it this week.

Six months ago we purchased a '91 Chevy Pickup and 3 months ago the truck started to "sneeze". Sometimes while accelerating the truck makes a "toot" noise from in front of the driver under the hood, and with the noise I have a momentary loss of RPMs. This can happen a number of times in a row, making pulling out on to busy streets difficult and dangerous. Most of the time, I take my foot completely off the gas and then re-apply it, and the issue goes away. It happens both with a cold engine and a warm/hot engine. This problem started when it was cold out (around 10 degrees Fahrenheit) and the mechanic I talked to about it thought it was the E10 87 gas I was putting in.
I switched to a 97 octane/no-ethenol fuel and the problem went away, until about a week ago when our temperatures finally broke 50 consistently. The problem is back and with it is a minor fluctuation of RPM when idling in neutral. The truck also created a new symptom, I was driving at about 50mph and the truck acted like it slipped on ice... I had evened out my speed and the truck seemed to start coasting then got back to driving at speed, it jerked the whole truck, like driving over a patch of ice. I don't know if it has anything to do with the original problem but all symptoms may be the same thing....
The truck is a 91 Chevy 1500K, 5.7L V8 and has 74,000 miles (mostly highway towing). It had been sitting 2 years, not really being used, before we bought it. We had the fuel injection system cleaned when they did the oil change, right after we purchased the vehicle.

It was running fine. tried to start and it just turns over. Also the fuel gauge doesn't move from an 1/8th of a tank. I took the filter line off, turned the key, and gas shoots out but the injectors don't spray at all. I poured some gas in the tbi and still just turns over without even trying to start.

I have an 89 Chevy Van. It has been sitting for 4 weeks without being started. I went to start it and no lights or radio and didn't even try to roll over. I figured the battery was dead so I went to jump it. With the cables connected the van started but once I removed a cable the van turn off! Is it the battery or is there another problem?

In the first two years of ownership of my Passat, when I would turn the car on during cold days, the rpms would stay at 1500 for a quick 20 seconds until the car got a bit warm and then would drop down to about 800. Recently, when I turn the car on cold days, the rpms drop directly to 900 and below.

I have a '89 Chevy 350 v8 in my boat. It starts fine, but then stalled when decelerating, and would not start. I smelled some gas fumes when trying to start it after it had died. It started up fine the next day without problems. The distributor was just replaced so I know that is good. Not sure if this is related, but occasionally it will diesel a couple cycles when I turn it off. Could this be the carburetor, or something else?

I have a 97 chevy and the only way to start it is to jump the starter relay, not sure if it is the key switch ot the nuetral saftey switch.

Chevy Celebrity ... Engine is 2.8 mpfi and I have been able to get it to start by pumping the gas pedal while cranking and keeping it running by having the gas pedal depressed slightly but as soon as I let off the gas the car will die. It has a new starter, new fuel filter, half a tank of gas, new battery...
Check engine light came on and i did the paperclip trick and it showed code 43 which was knock sensor.
