i just bought this evo 8 and wanted to see if it had the walbro pump installed so i took out the pump(it was the walbro) and i put it all back together and now the car wont start ?? any ideas...c wut i get for messing with stuff blah

 

check all the connections and prime the fuel system. im sure its just a bad connection. maybe a blown fuse at worse

 

i took it apart and put it together again ....how do i prime the system? should i hear the pump turn on when i turn the key on? i didnt check the fuse though i will do that now...thanks

 

just turn the key on and off but wait 5 secs between switches. do it about 5 times. i would leave the seat out for a better chance of hearing the pump.

 

It will probably be the fuse, however to prime the fuel system you simply continue cranking the car trying to start it. FYI after installation of the walbro pump it will take up to 10-12 seconds until the car will start.

 

another dumb question ...which fuse is for the fuel pump...ofcourse car comes with no manual

 

which fuse is the fuse for the fuel pump?

 

its one of the replay fuses under the dash -7.5 ...check them all i dont remember which one

 

checked all the clear fuses under the dash they all look good...what about the black fuses the bigger ones?

 

does anyone know the exact location of the fuel pump fuse?? i do not have a manual

 

Same here and mine is not priming and will not start...turns over but won't start.

 

Checked fuel pump for power? Checked all fuses? Hoses nice and tight?

When you turn the key with the seat and cover off do you hear the fuel pump? Should have a slight audible whine to it.

And sometimes it does take like 6-7 cranks of the key before it starts getting the fuel it needs to start.

 

2.3 stroker eagle crank, howards rods, je pistons
2 intake walbro 255s
AEM tuned on e85 etc.....yes I know the pump should whine with the key to on...which is why I stated it won't prime. I have had to prime the lines with the AEM for like 5 years now lol. The pump works out of the car and switching it with the secondary pump it also worked. I should have been able to get the car to drive home by using the universal relay to power the secondary pump but no worky....I am thinking maybe crank angle sensor. I dont think it is a pump or even a pump wiring issue since the car wouldnt even crank with the sec pump constantly running.

 

No ideas guys? What about the crank angle sensor??? Dirty or loose?
