You might want to put a fuel pressure gauge on it. I'd change the filter too. Check the condition of all rubber vacuum lines. These are notorious for getting brittle.

have you tried cleaning your fuel injectors? There is a cleaner that you put into the vaccum line that comes from the brake booster to the intake (so it feeds all the injectors all at once) it is called SeaFoam it runs about $8.50 a can. The directions are on the can.

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

This is a very common problem with the 2.2 Liter engine. The Cylinder Head Gasket has most likely failed due to expansion and contraction of dissimilar metals. The Cylinder head is Aluminum and the Cylinder Block is Cast Iron. The Cylinder Head expands at a greater rate than the Cylinder Block creating a Scrubbing Action on the Head Gasket. Another problem on this engine is the passenger side rearmost Cylinder Head Bolt is typically overtightened at the factory distorting the Cylinder Head and causing Gasket Failure directly around that bolt. I have had to resurface cylinder heads and replaced gaskets on many of these engines where these symptoms were described.

I disagree with changing the MAF sensor. I had the same problem for about 4 years until today on my 2000 s10 4.3 4wd 125K. It runs like new, and all i did was paid 6 bucks for a can of mass air flow sensor cleaner from auto zone. Try this!! it was awesome the results

1996 Chevy Astro V6 67K wont start when cold, needs engine starter fluid, ok when warmed up. Runs smooth. What is wrong?


I would say that the choke sensor (or whatever it is called) went bad & isn't telling the computer that it's cold & requires more fuel. Instead of starter fluid, did you try to push the foot feed 1 or 2 times?

1997 chevy makibu wont start tries to but wont start sometimes it will start other times it wont then it ill start n die in a few seconds whats wrong with it


I suspect that your fuel system is faulty. Check for a clogged fuel filter, or if your fuel pump don't run at all, replace the "fuel pump relay". Fuel pump may be faulty. Sometimes your fuel pump will run, but be too weak to hold pressure, which will let your car idle somewhat, but be too weak to run the engine at speed or under load.

Truck wont start unless i pour some fuel in throttle body truck quits after dumped fuel burns off


sounds like the fuel pump or filter needs replaced. pull out line off filter underneath and turn key. if fuel comes out slow try replacing filter and trying again. if pressure is still low fuelpump is bad or a blown fuse or bad relay.

did you check power and ground at the fuel pump connector?there should be power at two wires at the connector,one should have constant power with the key on and thats for your fuel gage,the other power wire should have it only when cranking or for about 3-5 seconds when the key is turned on,check both of those first and that will let you know that everything is fine all the way forward of that connector,also did u replace just the pump or the whole sending unit?if you just replaced the pump the connector that runs fron the sending unit to the actual pump itself inside the tank also goes bad on this setup too,look for brown or burn marks on the inside of the sending unit where this connector hooks uo,hope this helps
