Hard starting issue 98 v70xc

Postby rmv » 28 Jun 2011, 03:39

My 98 V70XC has had starting issues for a little while. Initially it would start fine first thing in the morning or after sitting for a few hours, and start fine if you ran it, turned it off, then immediately restarted. However if it sat after running for 15 minutes to an hour or two, it would turn over for a few seconds before finally starting. The problem has been getting worse. When it does start after cranking, sometimes gas is necessary to keep from stalling, but only one or two shots to the pedal. When running it has a normal idle and gas mileage is also normal.

New parts and service done include: oem plugs, rotor, cap, wires, fuel pump, MAF sensor, PCV replacement, serpentine belt, fuel additive injector cleaner.

Anyone experieence this sort of thing?

Do you have a CEL light on? Get it read. Check all vac hoses, fuel hoses, etc,.
1) Cam sensor (even if you don't have a CEL on) it should be stored in the ECU...get your car read (Autozone)?
2) Ignition switch (diagnosis by wiggling the key in the ignition with the vehicle running...if you see your dash board light-up like a Christmas tree, its a safe bet, that is the ignition switch).

Tried to replace the thermostat and coolant temp sensor ? I have a similar issue and did part of changes to try to solve it. Seeing your list, what's left would be the two items I suggested.

Been out of town for a while, did about 600 miles on a trip over the holiday. Got 29mpg flatland highway and just over 28 with the mountains of West Virginia factored in.
Anyway, there is no check engine light, no codes. Since its not throwing a code, makes me think its not a sensor issue. Thinking it could be a fuel pressure issue. Like I said new fuelpump/ fuel filter. Is the circular part on the fuel rail the fuel pressure damper or regulator on this model? And if its not the regulator is the regulator near the fuel filter on this model?

The circular part on the fuel rail is indeed the fuel pressure dampener but you could also check the injectors o-rings as well. Those are very cheap and it's a good idea to replace them since a leaking injector could cause those issues as well. That's what I'm doing on mine as well.
