I may request more information or provide an answer momentarily. Just a moment. Are you certain you aren't losing fuel pressure?

Not 100 percent in the fuel pressure
Automotive Expert
Understood. Try spraying a little starting fluid down the intake and see if she'll idle for a second.

I did that also and still can't get it to run
Automotive Expert
Okay got. Let's check for spark next. Have you done that?

Did a compression check 3 cylinders are 145 to 150, 1 cylinder is 80Checked the [spark plugs](/topics-spark-plug-nissan/) I have fire on all 4 cylinders
Automotive Expert
Did this overheat?

No sir I always made sure it had fluid in it and it wasn't drove very much after I found the leak in the radiator
Automotive Expert
80 is low. Anything below 100 will not produce power. These engines are known for head gasket issues.

Anyway to check that?I can't figure out why when I changed the cam and crank sensor it ran for 20 minutes perfect. Then I cut it off and it won't crank back up
Automotive Expert
Let's scan it for codes first.

Had a mechanic come over and run a scan we got no codes popping up
Automotive Expert
Understood. I'd like to see live data when cranking then. Particularly cam and crankshaft signals.

How do I do that
Automotive Expert
You need a scan tool that reads live data.

Can you rent them at the local part store or do you have to buy one
Automotive Expert
You may be able to rent one yes.

Can't find a place to rent one I can buy one would this work?
