Why my Chevy truck won't start? Seems like its not getting fuel.?

Question

1998 Chevy truck can't get it started now. Was able to get it started after using fuel injector cleaner in the past. Then it runs really bad.
Now it won't start at all. Had spark plugs changed. Still won't start. Trying to start it has ran my battery down.
Could it be the fuel pump, starter or timing change?

Answer 1

i own a repair shop,and you said even when it did start it run really bad,id say there's a good chance it may be the timing chain,all gm products seem to need new ones around 100 k on them,they was made of a soft metal and don't last as good as they should have ,id check and see if its getting gas and fire,and if it is check to see where the rotor button is pointing to,and line the timing ,marks up on it ,this will tell you if it has jumped or not,but be sure and check for fire and fuel before you do anything else with it,,good luck,i hope this help,s.

Have a buddy unscrew the gas cap and listen carefully into the fuel tank. While he's doing that, you turn the key to the "on" position (just before starting it). You should hear about 2 seconds of "whrrrrrrrrr", if not the fuel pump is bad or not getting power. If you hear that sound, go to Autozone and ask for a "noid light", they're cheap. Unplug one of the fuel injectors and plug the light into it then try to start the car. The light should flash, indicating the injectors are getting power.

add: That should fairly well eliminate the fuel system. Just for safe measure you may try replacing the fuel filter but it would have to be pretty dang bad to completely stop it from starting.

If all of that checks out, pull one of the plug wires off the spark plug. Carefully rest it very close to something metal, but NOT A SENSOR! While trying to start the car you should see or hear a spark. It may take some adjusting of the plug wire since it can be sensitive to distance. Some deep plugs may require putting a screwdriver into it and rest the metal shaft of the screwdriver NEAR (not on) something metal.

Fuel pump: Yes; Timing Chain: Yes; Starter: If it turns over then no if all it will do is click then yes; it could also be a clogged fuel filter, weak injectors, timing could be off at the distributor; with so little info it would be hard to tell. Does it turn over? Have you checked to be sure fuel is getting to the injectors? When this trouble started had the truck backfired? Was it missing? Sorry I couldn't be of more help.

Answer 5

turn the ignition on. you should be able to hear the fuel pump running. if your not sure if its running you can pop the hood and find the steel fuel line behind the throttle body. There is a schrader valve on it. push the needle in and see if fuel squirts out. keep a rag handy, its probably carrying about 55 psi. your starter is fine, and your timing is computer controlled so its probably okay too. chevy fuel systems suck in those year trucks. i've got a 97, and ive been through my fuel system more than once. if you run into more trouble email me directly, i'll try to help.

Answer 6

Two thoughts. First if the dry gas worked and got it running then it's onvious you had water in the gas tank. Now if it's doing the same thing everytime it rains it could be that the moisture in the air it could be that condensation is building up in the tank. Try the dry gas treatment again. If it works then run the tank down near empty and have it removed, drained and cleaned. If the dry gas doesn't work try replacing the distributor cap. Hairline cracks inside the cap can attract moisture when it's rainy and short out the ignition system. You can remove the cap and get a strong light on it to check for cracks or black streaks. Either one indicate cross firing which will kill the ability to start.

Answer 8

Some cheap trys--

One- change fuel filter located on frame.

Two-open hood at night and crank motor over, check for arcing from plug wires. If you see sparks, wire set is bad.

Three-buy a Haynes or Chiltons manual at parts house and use it to check for any trouble codes from on board diagnostic computer.Very simple to do.

Remember- motor needs fuel, air and spark to run. Air is kinda a given, so check fuel and spark.

Like the ads say 'it's a Chevy' CPU probably

Answer 10

It is possible that there is a sensor or 2 that has gone out. You will need to hook it to the diagnostic machine, and it will tell you which one (or ones) that are bad. Most places will hook it up for a few dollars or nothing. But the same thing happened on a van I had, and I ended up buying 2 sensors. I was able to install them myself though. If you get 2 at once, do not mix them up. Is your check engine light on or been blinking?
