Hi All,

Hopefully I can help you all help me

I just got this car, cheap cause it doesn't run. The guy I got it from said the carb needed a rebuild, i decided not to tell him that it is a Fuel Injected engine ( yes, it is still all original)

The battery was completly dead, so I put in an extra battery, got good voltage now.

The Fuel pump runs constantly, with the key on. the fuel pump relay keeps making a clicking sound.

The engine does turn over, but will not start.

Not sure if it is actually putting fuel out or not.

I did some reading in the Ogre's cave. The Tach does bounce a little when attempting to start ( ogre says that means that the ECM should be getting ignition pulses...)

The CEL does flash at me, not sure why yet, still need to pull codes, is it the same process on the DIS engine, as the regular 4-cyl or V6 ecm?

I am a fairly decent mechanic, but do not know much at all about the DIS setup..

TIA!

Okay, an update already.

The Battery I put in wasn't so hot after all. I put the battery on a charger and now the Fuel pump relay is working correctly, the CEL is not flashing at me, and the fuel pump sounds like it is working correctly.

I do not see any wetness inthe throttle body at all though, after a couple of quick attempts at starting it, will have to wait a couple of hours for the the battery to fully charge, and will go from there.

Thanks.

the hose under the intake has a plastic clip you have to pinch together to get it off. its probly got a bad oring or a bad clip. it should pop off fairly easy. i just had mine apart on my 87

good luck

I did some looking through the Archives, found this thread: https://www.fiero.nl/forum/A...020511-2-017133.html

That is my problem. The nipple has broken off, leaving the threaded part in the intake manifold.

I guess i am going to be pulling the intake manifold, very very soon

Not to hijack, but where does the other end of that hose go? I have an 88 and there is no such hose and I've had the car since nearly new. There is what looks like a factory plug in the bottom of the manifold, the same as the two on the front. The parts manual also shows three plugs in the 87/88 manifold.

edit: Here's the parts breakout---



The three plugs are #38 but #39 is the "control, htr wtr hose", p/n 10042695 similar description to the part used in previous years but different number. Maybe some came with the hose and others with the plug?

That hose (on the '87 Duke) is a supply line to the heater core. You could probably plug the hole in the intake for a temporary fix, assuming you can live without the heater (emphasis on "probably"). You'd also need to crimp or plug the hose.

It's the heater core supply line. #39 in the pic. It's underneath the intake manifold. It is a quick connect for a hose goes to a hard line that follows the right side lower framerail leading to another a quick connect on the lower firewall, after which it bends around under the car to follow the heater return line to the heater core. Both of my 88 2.5Ls had this line. Where is the heater core supply line on yours if it isn't there? Does your heater work? Maybe someone disconnected it and plugged it.

I live in the denver,Co area.

The average temp around here has been on the mid 30's... I think a heater is going to be required to drive this car!

On my way to pull the Intake manifold.

Wanders off, with shoulder's slumped...

I have an intake manifold off an 88 if that works for you.

Well, I have discovered that the passenger side interior floor pan is rusted through. That on top of the intake manifold needed fixed/replaced is just to much for me to keep this car.

I am going to be parting it out.

Keep an eye on the Mile high Fiero's website, as well as the mall and Ebay!

Thanks a lot for all the help, i appreciate it.
