hi my name is ***** ***** ii can help
is the service engine soon light on ?
Hey there, sorry it looks like Clif stepped out.
If you have no spark on these engines there is generally only 2 "common" causes. By far the MOST common thing for a no spark issue is the cam sensor. It's located on the cylinder head just below the oil cap and secured by a 10mm bolt.
You need a lab scope to see if your getting a reference signal when cranking the engine and see if the reference it consistantly the right voltage by looking at the wave.
The sensor runs about $75 at the dealer if you just want to replace it, or you can pay a diagnostic fee which runs about $90.
not sure what your talking about?
WITH NO CODES, the other issue we see on these engines specifically is timing chain issues.
Crankshaft sensor back of the block near the oil pan, but I don't see them fail often and when they do the engine will still start just be in limp mode and not let you rev it very high.
I know you said you don't have any codes, but is there other details your keeping from me? Does the condensor fan come on with ignition in ON position?
The condesor fan is a control unit failure fail safe function.
Whats the history behind this vehicle?
ahhh probably have the flywheel alignment off then.
Should be a notch at the flywheel and a dowel pin hole to align. The dowel pin hole should be the one that looks like a square inside the hole.
but now that I recall you said you pick up an RPM signal when cranking.
I am starting to believe this might be a little more difficult than most issues that can be resolve over the net and require a more hands on approach. Knowing the extent of the motor replacement now really expands the posibilities for errors and the engine is going to have to be looked over thoroughly.
