After putting everything back together after replacing the intake manifold gasket the engine is very hard to crank but every once in a while (4 or 5 start attempts)
it starts perfectly and runs great, but if I turn it off it goes through the same thing again hard cranking.
Is it possible the rotor or distributor is on backwards? (I changed the rotor and am pretty sure I put distrubutor back in same spot but just trying to think of what it might be or would it not start at all if this was the problem.
Would a crankshaft position sensor cause this behavior? I don't have andy code testers but would go get one if this would help diagnose.
I am trying to narrow down the possiblilities before taking it in for a diagnosis.
If the engine is out of timing this will happen. Most of the time when you take out the distributor, even if you mark it, you have to have a scan tool than will display the cam position offset to set the cam position sensor to 0* +/- 2*.
