94 Lumina APV Starting problems

[bobd05]

Occasionally when I drive the van for a few miles it wont restart.It turns over but sounds like there is either no gas or spark.It never happens when Im somewhere I can check either of these things.If i wait a while it will start normally.It isnt running hot.Any ideas.

probably a crank sensor or ignition module going bad. It could also be a leaking fuel pressure regulator. You'll need to check for spark when the van wont start to determine which is your problem.

Thanks will try that.It seems this time when I start it and step on the gas while in park the engine seems to lose power about 3/4 of the way down.

That may be the rev limiter kicking in...it'll cut it back at redline.

Don't rev a motor that hard, unless you wanna see pieces of it fly through the hood.

Thing is it wouldnt even rev that high before it kicked in.It cuts out around 2500 RPM.I would hope a V-6 could rev to 2500 without coming apart.Could also be Im spoiled by always driving a V-8.I did drive it and it seems that it only does it in park and neutral.thanks for the heads up.

check the oil sending unit. if it has 3 wires short out the 2 across from each other at the plug it takes 2 min. and a paper clip. sounds stupid but fuel pump won't come on if oil pressure is low.

Thank you.I will definitely try this out.
