My 88 Camaro V6 is taking a long time to start. 2,3, sometimes 4 seconds of cranking before the engine starts. Within the last year I've replaced the distributor, plugs, plug wires, several sensors, pretty much the entire fuel system (getting fuel is not a problem I'm having)and replaced the starter a year and a half ago. Any ideas?

Can your hear the pump run for 2 seconds with key in the "on" position?

If the fuel pump relay failed, the oil pressure switch would have to close before the pump would run.

[img]graemlins/beers.gif[/img] Joel,

Long time no hear from you, I thought you had gotten that beastie up and running strong. If you still have that information I sent you about a year ago, you might want to break it out and take a look at it. While you were working on it, did you by any chance take a look at the cold start injection circuit. Just a thought!!!!!!!!!!!!! [img]graemlins/thumbsup.gif[/img]

Thanks for the reply. What's a cold start injection circuit and where might it be located?

My dad had a couple of S10 pickups from the 80s and 90s. One had a 2.8L, the other had a 3.2L engine (I think it was). Both had trouble starting. Seemed like if you cranked it, stop and cranked again it would fire right off the second time. We never knew what was causing it and never spent much time finding out. I'd be curious if the second try is the charm for your engine. Not that it is a fix, but might lead us toward a potential cuase.

My old 90 S-10, 4.3 litre, It would crank and crank untill the cows come home befor starting,
I checked fuel pump, actualy replaced it, did an injector flush, spark plugs, cap rotor wires,
this thing just would not start, eventually the starter fried and I had to replace it too.
I was so d#### frustrated that I replaced the nearly new ( or so I thought ) fuel filter.
It was plugged solid, never had a problem with excessive cranking again. I just changed the filter in my daughters 89 Z24, and it was partialy plugged, real hard to blow through, and it is just over 1 year old.

Thanks for the responses. I had the timing adjusted at a shop about 4 months ago, and since then, I've lost an alternator, a battery, and the car takes forever to start. what do you think? Timing problem maybe?

you think 4 seconds is a long time for it to start? if it has sequential efi, it might take a few revolutions to figure out when to fire each injector. hell, the brand new 2002 Silverado HD i had took a few seconds to start.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?
