1st bump

 

don't bump your thread after 11 minutes please,

how do you know there is no preasure? do you hear the fuel pump? Is it out of gas? give us more information. did you check to see if the pgmfi main relay is latching, you should here is click and then the fuel pump will prime.

 

no prime anymore...no pressure on B&m fuel gauge like below 10 psi, no click nor prime, = F*CK FUEL PUMP?!?!! ....yea or nay?

 

start by replacing the PGMFI main relay, if you knew alittle more about cars i would say before you did that you could apply voltage to the fuel pump pins to test the pump, but that requires alittle electrical knowledge and a who lot of explaining on my part.

did this just happen out of the blue? do you have a chipped ecu or anything? an extention harness at the ecu?

like i said before MORE INFO will help

 

yes ...i swapped ecu p13 from a chipped p72...my friend told me his p13 wasn't doing good...stock...even mines...he also said it may be the main relay underneath the dash....no pressure going into the injectors and such....where can i get that info at?

 

to add....i used a vafcI and i splice the wires to connect to the A-B-C plugs but nothing out of the originary. I taped them up after usage. i think it was the ecu...it never happened b4, why now, i took it a car wash. This WORKED, i hit hard underneath the dash with my fist and tried restesting the ecu and also unplug the map sensor...waited..waited....then put everything back...after that it worked like new....THEN NOW IT DOESN"T again...

 

bump..HELPED>....main relay...or try a different ecu...who gots a virgin p72 i can borrow ..pretty plz
