HELP! Car won't fire after Turbo Install

[RedFR-s]

It was the MAP sensor got it running this morning.

On my drive home from the tune my fuel pump cut out. Made the 8 pulls on the Dyno and about 35/75km on the highway with some pulls getting there.

I could feel it leaning out as I drove but didn't realize what it was and it just kind of cut out on me.

I have the AEM 50-1210 pump but had to force the canister to get it to close. I'm worried I've choked out the sock and have blocked fuel to the pump.

Anyone installed one of these? I got 3 o-rings, pump clicked on, couldn't get the clips from the housing to the canister on though. Just kind of jammed the canister in close the tank lid.

If you were able to get it on with a little force I would say that should be okay. If you are worried, pull it back out and drill some holes and secure it using zip ties. That is what I had to do with the Full Blown pump, and it worked great for many miles with the correct number of O rings.

It was ALOT of force. I had to lean on the whole thing. to get it clicked in and to get on the tank my buddy pressed down on it while I threaded it on. I'm worried I choked out the pump with too much pressure.

I think you need to do what King said and pull it out, secure with zip ties or cable ties. Even if the tank lid itself if holding it down, i think over time and vibration it will have a chance to move a bit. The O ring area is very sensitive and just moving it out of place a bit can cause the fuel pressure to be lost right there.

chocking the sock is a good second theory although I don't think that's it.

here is what I did on mine to secure the sock.

Turns out a coolant line exploded and the engine overheated but shut down before any damage occurred. I've got better lines on it now, but I still have the leaning out issue.

My pump came with it's own sock so i don't think that's the issue. It was getting the sock, pump, and hoses secure in the canister that was the problem. Should I drill holes in the side of the canister to secure the pump assembly to then?

Was it an Omni 3-bar MAP sensor by chance?

FYI, they go bad often, I also bought one new that didn't work. They are garbage.

Get a Denso or Bosch MAP sensor and don't look back.

I'm having a similar issue with my setup, I've got a 4bar Omni map sensor, have you changed from the oem one back yet and got it all working ?

I unplugged mine and it ran. Needed a tune to compensate for the 3 bar sensor.

Update:

I've had just about every problem under the sun with this damn turbo. it wasn't the pump driving back from the tuner, one of the coolant lines over heated and blew spewing my coolant everywhere. engine overheated and cut, luckily no damage. Put on appropriate lines and no issues since.

The car is hesitating under load. I'm waiting to get a wideband installed so I can figure out if it's lean or rich, but I'm thinking starvation. I took it to a shop (way to frustrated to trust myself at this point) and they are saying pump and injectors are good and it's a tune issue.

Driving home from a car show this week I had major hesitation and rough idle causing a stall. One of the vacuum lines failed causing a vacuum leak. I was hoping this was the main issue, but the vacuum leak is fixed and I'm still getting hesitation under load.

I'm using a tune that was on this kit on another car that worked perfectly. I'm out of ideas at this point. I've got my tuner saying its mechanical and my shop saying its the tune.

I did find a loose v-band, but its connecting the wastegate pipe to the waste gate, so it should have any impact on the AFR. I can't get at it with the tools I've got right now without taking some major parts off the car.

Found this thread today, my issue is identical (I think) not sure what the tune changes were though. My tuner came highly recommended from other 86 owners running all kinds of boosted applications. Mine was tuned on a dyno.

If you're running a stock tune with an aftermarket MAP sensor, it probably won't fire. If you put the stock MAP sensor in, it should start.

If that doesn't work, my guess is fuel pump.
