car wont start... fuel pump?

tgeorge33 · 08-09-2018, 07:00 PM

hey everyone.
finally got my Z back from paint

, drove it over the weekend, no issues

. came out Monday to take the car out. it started up fine, then all of a sudden it bogged and stalled in my driveway. tried to start it again, it would crank but just wouldn't turn over

. i don't hear the fuel pump prime anymore. (walbro 450 F90000267). i checked all the fuses, they are all good. the connectors look clean with no corrosion. so next is to test the connections, although I DON'T KNOW which of the tiny prongs are what so i don't want to touch the multi meter needles to anything.
can anyone help?
or should i just switch out the fuel pump?

I would put money fuel pump top hat failure. You need to get the top hat replacement from phunk...CJ Motorsports.

Fuel pump hat failure is more common on our cars than you would think. It could be fuel pump failure and/or fuel pump hat failure.
