After a LP hard start
My friend has a 98 24v and the stock LP took a dump so he put a 100gph carter on it and took the fuel line strait from the carter to the fuel filter housing and bypassed the stock LP and now it starts hard, Any Ideas??? we checked for any possible air leaks and we cant find anything that would be causing this
|
how does he have it wired in?

He wired it in using the stock LP power source

just for grins try a different lift pump like a stock carter....we have seen more then a few cases with the airtex replacement pumps cause a hard start, after talking with bosch about the problem it seems that the ecm calulates the pressure by reading the amp draw on the lp circuit and the pumps are not drawing the same current and it sends a false signal to the ecm and causes a hard start, i've even heard of this problem with the fass direct replacement pumps but i think they have since fixed theirs

Ok wil try that, Thanks for all the help man! I greatly appreciate it!
|
no problem, let me know if that changes anything

A hobbs oil pressure switch will bypass the ecm. That's the first time I've ever heard the ecm makes pressure calculations according to amperage draw speculation.im going to do some research on that subject. Considering the variables it would be difficult at best but in the same respect I rarely use factory fuel systems or ecm/pcm wiring.
