THIS SOUNDS LIKE THE FUEL PUMP PRESSURE MAY BE DROPPING OFF AFTER SHUT DOWM, THERE IS A FUEL PRESS CHECK VALVE BUILT INTO THE FUEL PUMP TO PREVENT THIS, U WILL NEED TO DO A FUEL PRESSURE LEAK DOWN TEST, IT SHOULD NOT DROP MORE THAN 5 PSI AFTER ENGINE IS SHUT OFF, IF IT DOES THE PUMP MUST REFILL THE FILTER AND SUPPLY LINES WITH FUEL THIS CAUSES STARTS AND STALLS AND LONG CRANK TIMES.

If the engine is using a carburetor, the top gasket maybe leaking evaporating the fuel in the bowl. Check or replace the solenoid switch on the starter body.

The click is the starter solenoid. It's closing the circuit to send current to the starter motor. The starter motor is either bad or the solenoid is defective. Once in a while you have a bad connection somewhere, but 99 out of a hundred times it's one of those two. Have a local shop troubleshoot it and fix it for you. Go to work, make some money, pay the shop, everybody's happy. It's the American way.

Check air filter, maybe clogged. Check leaks of vacuum on the intake manifold, maybe a broken hose.

Has it been sitting up all winter? If so, you might need to drain fuel from the carb and replace the filter. It sounds like a fuel problem to me.

Won't start without ether...will run fine after starting...it's not the starter or battery...that stays charged....thinking fuel problem...a fuel pump is very exspensive so just trying to see if it is...


That engine uses a CPI fuel injection system. It quirks a minimum of 58 psi to start. As little as 1 psi will cause it not to start. Once it is running it requis less fuel pressure do to the poppet injectors being under vacuum. Check fuel pressure with a good gauge. If you see less that 58 psi replace the pump.

I replaced my water pump in my 1999 gmc yukon my check gauge light stayed on and temp gauge stayed over to hot side. can i reset it?


Not exactly.
The check gauge warning light is on because the temp gauge is reading hot.
Does the temp gauge read hot as soon as you turn the key switch on, or not until the engine as run for a few minutes ?
If it reads hot without the engine being started, there may be a short in the wiring or the sensor may have failed.

My 1998 dodge caravan won't stay running. starts up but shuts down instantantly or when i take my foot off the gas pedal,


ok i have a 1998 durango with the 5.2L 318 engine. had trouble with a bad cell in my battery. I went out bought an optima red top battery for it 800cca. put it in and had same trouble. No start without putting foot on gas. wouldn't stay running without holding foot on gas. CPU has to relearn it's programming once you unplug it for long periods of time. mine was without power for about 2-3 weeks till i got new battery. Start with this.. first check under air filter make sure a squirrel hasn't made a mess under your air filter and it's clogging the air intake. Then pull off the lid to your injector cover ( the screw down lid coming from the air box ( with air filter in it) to "carb") make sure all your cables move freely. put that all back together and close hood. Start truck with foot slightly on gas pedal to get started. keep it at about 1k to 1500 rpm for about 1-2 minutes. Rev motor to about 2500rpm and let it die out if it will. Get out lock doors with key fob if you have it. if not make sure to lock doors. ( trust me it worked for me) let sit for 5 minutes. come back out and unlock door and relock door 3 times with fob ( if you have it ) or key if you don't have a fob. Then unlock it with the key and enter vehicle. Start truck as before and keep it around 1k to 1500 rpm again for about 30 seconds rev it up and should keep running. Mine did. I think the iac was stuck from sitting and has now since loosened up.
Good luck hope ti works for you.

1998 Volvo S70 stalls intermittently


Have tried getting quality gasoline at a reliable station? It sounds like water in your fuel system. Add a couple bottles of Iso-Heet fuel system dryer everytime you fill up the next few times, and that should cure it.

93 yukon wont stay running wont start unless u put gas in tbi?


Not sure of your question, but it sounds like a bad fuel pump or clogged fuel filter. If it stops running after gas in tbi is consumed, it is likely the fuel pump.
