87 T2 Crank no start, has compression spark, no gas to plugs
87 T2, crank no start, changed spark plugs, compression good, has spark - fuel was old so drained tank completely , cleaned, filled with fresh gas. Still no start.
Removed fuel filter - full of old dirty gas. Replaced it - still no start. What gives? Going to tackle the pump next but weird the filter and leading fuel hose was full of old gas yet it still will not start. |
if you jump the fuel pump does it work?

its pretty easy to jump the test connector and see if the pump runs.

Well, that would indicate that your fuel pump relay is flipping, since that's where it's located, but if you dont hear the hum of the pump, then you're gonna have to start at the pump. It's under the metal cover in the trunk. The cover plate is 4 phillips head screws, and then you remove it from the tank with another 8 or so screws. you may just have a bad fuel pump.

I have it almost removed, the screws are minty clean but I am confused about the black circular plug that sits on top, should that be removed? |

its just a rubber grommet to hold the wire in. It presses in and out you can remove it and it will make your life a bit easier. Fits in pretty well but just give it a little push with something and it should come out

if its not, the fast idle is done by a thing called the thermal-wax which is a wax pellet that pushes the throttle open when its cold. in addition to being old, the hoses can be full of air, or clogged |
