87 5.7 TBI Died

[Sgt Hollywood]

So my 87 Short bed (350 tbi) was running great last week. Then while cruising at 65mph on the highway it lost power, luckily I managed to hit the off ramp on the down side. Having limited tools with me and being 2hours away from home I was a bit in a jam.

Checked the filter and I do get fuel spray from both injectors, but how much is a question. But it only idles very roughly (with a little pedal work) and if you try to give it gas it boogs down and will stall out. You can hear the pump prime when you turn the key.

I also don't get an engine check light with the key in ignition and don't get any error codes. The latter is strange since I'm sure there's a few in the system.

Right now its in the closest shop but I'm not sure if they put a gauge on the output pressure.


So I'm thinking Fuel pump or ECM(?)

For point of reference in case, any idea which pump and sender unit a 87 350tbi with 16 gallon tank would use. I'm seeing a couple different codes VEH VEX. Any source you guys would recommend if I do end up needing a new ECM. 1227747 ACSF.
