Hello,

Have a 05 SE 2WD that all of a sudden has became very hard to start. I have no codes showing. Have to floor it and crank it for roughly 15 seconds each time - even after it warms up - any suggestions?

Thanks

The failing crank position sensor or failing cam position sensor (there are two) can cause this on these vehicles and they don't always trigger a code. But with what you are describing, I would perform a fuel pressure test and fuel pressure leakdown test, as a failing fuel pump can be the problem.

Change fuel filter and check fuel pressure at fuel injector rail should be 32-34psi. Maybe the fuel pump is too old and worn out. Try changing all the spark plugs?

Thank you. I thought it may be plug related but didn't think about the fuel pump going out. I just replaced fuel pump on my 86 Z as it completely died w/o warning :)

Fuel pressure on an 05...which has the VQ40DE engine....is 51 PSI and there is no serviceable fuel filter, as it is part of the fuel pump module. You need a special "T" adapter that fits between the fuel rail and hose on the driver's side and you need a special fuel line disconnect tool to fit in between the fuel line and rail, such as Lisle # 39210. If you spray some carb cleaner into the engine and the engine fires on it, that would be an indication that the issue is a fuel delivery problem. If it doesn't, the check for spark.
