I installed this MPFI manifold on my 91 Suburban, 350, VIN K, V2500.
The motor has just finished being rebuilt, everything is new or made the
trip to the machine shop. As far as I can tell, all wiring is good, I
have rechecked and even re wired just to be sure. I wrote an earlier post
about stabbing the distributor. I have been doing it correctly. The truck
will only start with the gas mashed to the floor and dies if you adjust the
dist or release the throttle. There is spark and fuel, maybe too much fuel
, I dont think it is a timing problem anymore. I got a couple of
1. Has anybody got any tricks or tests to see if the MPFI is functioning
2. Fuel pump is either on or off correct? There is no different voltage
or speed to the thing is there?
3. Why in the world would exhaust be coming out of my throttle body?
I thought maybe it was a timing issue once again but would the truck run
at 180' out of alignment?
Edelbrock only instructed me to check the fuel pressure which I plan on
doing but if the truck runs isnt there atleast enough there?.....
Anything would be helpful...
