Please Help 1993 Volvo 850 Hard Starting Issue
Posted 10 May 2006 - 02:19 AM
Car will sit over night or for a few hours, and when I turn the key it will keep cranking but will not start UNLESS I press the gas pedal, OR turn the key off and try again real quick (starts right up then!)
Almost like it isn't keeping fuel inside to start it... any ideas?

Have you ever changed the fuel filter?

If there are some anomolies in the above, I would investigate further. If not, could be spark related. I once had some trouble getting the car to start when my battery was weak and would not crank the car very fast. The battery was replaced and I no longer had any hard-start issues. If your rotor and cap are old I would probably replace. Seems like the iginition system doesn't have much tolerance for worn parts.

If I were to guess, maybe a dirty IAC (idle air controller)?

The idle air controller is the silver cylindrical unit thats mounted horizontally near the throttle body and vaccum tree, there is a sensor coming off of it and the throttle body hose has a small artery that connects to it.

Problem: traced to a set of bad injectors! Went crazy until the mechanic took the injectors out of the engine, but still connected to the fuel rail. AFter 1/2 hour, he noted that several were wet. Not supposed to happen. One was really damp, while others were just wet. Car had 160K miles on original injectors. Replaced the injectors with new ones from FCP Groton, and the problem immediately went away. The problem was hard to diagnose, because the system retained fuel pressure, but the leak was just enough to make the car too rich in more than one cylinder, and that made it harder to start.

Could the smell of gas mean anything? Not sure if I over filled it when refueling or something leaking..I see no leaks
