So we just went and picked her up! Theres no battery so we havent tested anything yet. We had to do some brake work to get it to move. Removed rear pads and gave the fronts a lil pry bar. We pushed onto the trailer and its now in the driveway.





Guys been going out and pouring a lil oil into the cylinders every now and then over the years. He says once a week. Theres a long metal funnel and a jug of marvels in the trunck. All the cars he had were well kept. Met him at the car show last weekend. Anyway where to start?

23828 miles? Wow!

Battery. See if the fuel pump runs and check the condition of the gas. If it doesn't run or the gas is funny colored, smells like varnish, then drop the tank.

Try to turn the engine over by hand before using the starter.

If he's been putting marvel mystery oil etc in the cylinders for years then you probably should change the oil before really starting it up.

Was it stored inside or outside?

Check the heater ducts, under the center console, and around the tail lights for mouse nests. I got one that had been in a barn for 8 years and had all of the above. (It was in Maine too.)

If he put that much oil in the cylinders then its best to remove all the plugs and suction it out. You'll never start an engine flooded with oil and if the engine encounters a full cylinder on the compresion stroke when starting it will either stop or in the worst case crack the rings and/or break the piston ring lands. Once the oil is out and after you have cleaned the tank out, changed the fuel pump and put fresh gas in it, it should start but will smoke like hell until all of the mystery oil is burned out. This may take a few minutes and you will create a smoke screen in your neighborhood. The good news is that if the cylinders were preserved in oil the engine should have good compression. The bearings may have a flat spot on them from sitting so long but start the engine and listen. You may luck out.

No fuel pump whirring. Threw a battery in and all of the accessories work just no fuel pump running. Cant get in to check the fuses cause the cars drivers side is against the house tight so the bikes can fit in the driveway. More testing to do. Guess I'll check for power at the connector on the engine firewall, that should tell us a thing or two

What size is that main pulley bolt? The one that I can turn the motor with? Couldnt find that imfo anywhere. I'm gonna need to run to the parts store to get that one socket so we can see if the motor will even turn. Just cant figure out what size that bolt is..




A little dusty but otherwise looks to be in good shape.

24mm...I believe a 15/16" will work as well.

The advantage of this forum is that for anything you could possibly need to do, there is someone else that has done it in the last couple days. I did walk out to the garage to verify I remembered it correctly, though. Takes about 50 lb/ft of torque to turn it past the compression cycle...if it takes more, then something isn't right.

Q1 - Does the check engine light come on - key on engine not cranking? It should. If no SES light and no fuel pump - then look to see why the ECM isn't running. First suspect is the ECM reset connector is unplugged.



Q2 - Does the fuel pump run when you unplug the fuel pump relay and short together the pins with the Orange/Black wire to the Tan/White wire?

The fuel pump relay is located IN the engine compartment, on the firewall, behind the drivers seat. There are usually more than one. The one you are looking for have those two wires running to it, along with a Green/White (gets +12v from the ECM to turn on the relay) and a Black wire (Ground)

I can hear the fuel pump relay but no fuel pump whirring when I switch the key to the run position. Which of the three wires are the one I need 12v at on the fuel pump connector on the fire wall. I think the brown and white is ground but dont know the other two wires. The Haynes doesnt show this in any of the wiring diagrams... typical

Yea cowspatoot great help here on the forum, saved us on our other fiero big time!

Gonna get some ramps over here tomorrow and maybe pull the tank. Think ramps in back and jack stands in front will be enough to pull the tank? Maybe have to wait and see if we can get the motor to turn then go from there I guess.

edit, typo

Tyvm Phonedog Will do these test first thing tomorrow. I can hear an audible click sound coming from the relay so I think that maybe okay. Regardless will do the test you pointed out first thing. Thanks again

Edit; yes we have the check engine lights coming on
