Hard Starting

Tschadt · Post by **Tschadt** » 22 Jul 2009, 18:12

I have to crank the engine 4 or 5 times to get it started. Did fuel pump, fuel filter, Volvo did throttle body, crank sensor, cam sensor, oxegen sensor, cleaned MAF, Immobilizer antenna, new keys, Mechanic checked all sensors, with that machine. all check out within correct range, with engine running, and with engine off and key on. No codes present.Good fuel pressure at rail. When she starts, she runs great, good power, good fuel economy. same situtation cold or hot. Driving me nuts for over a year! Volvo had the car for 1 month, gave it back and was alright, (not good) for about 1 week. Now back to the same situation. What else could it be?

Battery and plugs seems like a good place to start if you ask me. If any of those other things had been bad you would have popped a code.

CRC MAF cleaner worked for me. Not a whole lot to a MAF really, electronics-wise. Should cost like $20 new if you ask me. Somebody's making a killing on those.
