Just flipped out the spider injector unit with a new one. Took out of a test drive to the car wash and to run a few errands. Got it home and turned it off.
I then immediately tried to start it again ..... it started and was idling rough all of a sudden then died off. Tried to start it again and it started but idle and stuttered then died.....Tried a third and fourth time and to no avail it will not start......

No trouble codes are coming up......

Any suggestions ?

Before I put the new injector unit in I checked the fuel pressure and it was checking out good....


I guess the only thing I can notice is that it's hot now and that's keeping it from starting.... I'm going to let it cool down and see if that allows it to start.

Thanks for any input !!!

 

Why did you change out the spider injector? I would check the fuel pressure again. Change the fuel filter. Remember you can have pressure but it needs to be in the 55 psi or higher!

 

I changed it out because it was old and gas mileage was crap. The fuel filter is fairly new ( 6 months old ) ..... Have changed out plugs, rotor, cap, wires..... When I checked the pressure before the spider install the pressure was 55 to 60 range....

thanx for the input / response.

 

It should still start when it it is hot. If that were the case, I would never drive my truck here in Florida. Still seems like a fuel issue. Keep checking. Like I said, check the fuel pressure again.

 

Boom. Just checked the fuel pressure / first tried to start it and no dice. Checked the fuel pressure and I'm getting nothing. Straight up zero....


The thing is I've never been able to hear the fuel pump on my hoe...
I swapped the pump around 50k ago.....

 

Is there an electrical connector or sensor that would shut my fuel pump down / off for any reason .. say a bad coolant temp sensor.....
