Your cranking voltage should be higher than that. Below 10 volts some ECMs will not work because they will not give sufficient voltage to controls and sensors to function. You might want to...

I always leave the key on for 2 seconds then start. Insures good fuel pressure. But you need to have good cranking that does not draw on the battery too much. What does your voltage look like when...

The Renix needs three full cranks, plus proper fuel pressure before the ECM will allow the engine to start.

It is just taking that long to develop sufficient pressure.

Personally I would just get the regulator. It seems to be what fails in these assemblies.

I guess one of the factors I would consider is who made them. You usually cannot go wrong with Bosch, but it is twice as much. I have also had good luck with carter fuel pumps

Tony, I believe on the 98 you have to drop the tank and pull the sending unit which is in the top. Somebody on Cherokee Talk found a pressure regulator seperate for not much money.

On the bright...

When you turn the key on, the pressure should come up within a few seconds. Within about 3 seconds it should be at about 50 psi. Then it should maintain it for at least ten minutes, but in reality...

It is not the logic here I am questioning. But generally, when there is a slow start after sitting, it is the fuel pressure that has bled off. Then it is reestablished and starts right up. How...

Hey Tony, I suspect you are having the fuel pressure bleed off when it sits. If you have a fuel pressure gauge, you might check that.

look on the bright side, you get better than some others:sign0181:

Second one sounds good Tony. I have to clean mine now. It sticks on start up. It is your fault. You gave it ideas...

Muddy, I would check that fuel pressure on that first crank. You might find it low.

Muddy, first guess is fuel pressure is going down after shut down. Hook up a gauge and check it as someone tries to start it.
