I replaced a bad fuel pump (Walbro) , and it starts and dies after running for a second. I am not sure where to start. Ideas??

She only has 41,000 miles (Body is rough)

 

does it have the old gas or good new gas? Check for vacume leaks and if the AFM is connected

 

jump the fuel pump test plug and see if it starts.

Who in the Hell would abandon a TII in a field after only 41,000 mi's???

Good find, good luck with the project.

 

if its been sitting that long, prob is a little low on compression. I bought an 87gxl that had been sitting for a year that had similiar probs. Put a little atf or MMO in it.

 

I had to outboard power to the fuel pump to get it to try and start (No power at the fuel pump). The tank was almost empty and I added about 4 - 5 gallons of fresh fuel.

Where is the fuel pump test plug?

 

If its the same as an N/A its the yellow two plug test connecter on the passanger side strut tower.

 

how much did you buy it for?
maybe you should replace ALL the fuel lines and check all the vaccum lines while your add it! It could even be really dirty injectors, put some STP fuel injector cleaner in your tank and try to keep it running for a little while!
