Question about 1996 GMC Sonoma

3 Answers

Unsolved Problem! Please HELP! I have a 1996 GMC Sonoma truck. The PROBLEM is when the truck sits for a long period of time especially over night, it takes about five tries for me to START it. I have REPLACED the fuel pump, regulator and filter. New spark plugs and ignition coil. New rotor and distributive cap. Plug wires and battery are good. Used H-44 to clean the fuel line. Brand new starter. I am a woman who LOVES her truck!!! Please help! No one on my end can seem to figue this out. THANKS!

    It takes about four to five tries of turning the key for the STARTER to kick in

    It takes about four to five tries of turning the key for the STARTER to kick in or should I say for the truck to START!

    Hi, I think I can help, but need some additional clarification. What exactly do you mean by "five tries" to start it? Does that mean that you turn the ignition key 5 times before the starter will do anything, or that you crank the engine for 30 seconds 5 times before it starts, or that it starts and then dies, but after 5 tries it stays running, or something else? Once the engine starts, is the check engine light illuminated? If so, can you get any stored codes? (Many auto parts stores will scan codes for free.) If you can post any stored codes here, that could be helpful.

Pin hole in gas air till gas comes back up to two lines jumped out of plastic retainer on frame...corner of gas tank wore one hole in each line... [one is a return line]... had to loosen tank straps & filler pipe...slide tank back to access where holes were..cut rubber gas line long enough to cover holes...clean metal line as clean as possiable... cut rubber hose long ways - 1/2 way through....slip over line...slide down to cover hole's ...turn cut side of hose to the reverse side of hole's....use small gear [screw] type clamps...[i needed 4 to cover length of hose] ...tighten securly...i used a socket & ratchet for max tight...covered both with a piece of inner tube to protect when placing tank back into for me without replacing both lines because of two small holes

My truck did the same thing, only mine turned out to be the starter was not shimmed properly and as a result it developed a bad spot on the starter thus the 4 to 5 tries to even get it to turn over. The starter ultimatley caused the wires coming from the alternator on the right side of the engine to catch fire due to the streess of all the voltage, causing a total re-wire on that side of the engine.

Have you looked at the gas or gas tank. It could be full of water. Your specific pump could be sitting up high where the gas water line settles after a period of time. Try some dry gas and run the tank out.

1996 gmc sonoma, wont start, if i prime it it will start then it dies, already replace the fuel filter and fuel

Have you hooked up a preesure gauge, if youre priming it by turning the key a few times i would say you have a fuel pump thats low on pressure and probably should be replaced.

My 1996 GMC Sonoma is cutting off intermittently. After it sits a couple of minutes it starts back up. Could this be the timing chain.

Its not a timming chain, When was the last time the fuel filter was chg.? If you can't remember chg. it. If that don't help. Do a fuel pressure test to make sure its not the fuel pump. If that chks. out ok, then your problem is electrical, witch could be ignition switch or ignition madual. Find yourself a reliable shop that can do the tests for you if you can't do it yourself.
