Hello, I need some advice on this rig. The customer stated
that two days ago after coming off the highway the Van
began surging and then stalled. It would not restart for
three hours. He drove it several miles and it repeated the
same, first surging then stalling and no restart. He drove
it in today and it sat for two hours and then it would not
start. After pushing it in and testing spark, ok at that
time, then fuel injector pulse the thing started. It ran
for over an hour but idled rough. I tested the temp sender
resistance-was ok. Then I tested the voltage based on the
Vantage it was way off. When I disconnected the temp sender
the pulse width went up from 3.08 to 3.4 and the idle
smoothed out. Based on the vantage voltage readings I
replaced the temp sender only to find it identical to the
old one. The vane air flow meter is reading 1.36 at
idle-Vantage spec to 1.15. I could not get it to not start.
Any ideas on what to check? Thanks for the help.
