Fuel pump issues - corrado wont start!
« on: Jun 30, 17, 09:55 »
Hey everyone,

The car:
91 G60
227,000
SNS chip
Stage 4 Charger with stock pulley.
All belts, fuel lines, etc are in perfect condition.
Fuel filter down before being parked for 4 yrs.
No leaks anywhere.

So here's the deal. This issue started just before parking it for 4 yrs. The car is now up and running perfectly except for this issue. The problem persisted after the fuel filter was replaced before being parked.

Gas gauge doesn't read accurately informing me that I'm in the red empty zone only after 200km of driving not hard. I fill it up and it takes 32L. This should be half a tanks as Corrado's have a 70L tank.

Speed gauge seems pretty accurate after comparing average speed to the people around me on the highway.

Rev gauge sits at 0 until I push the engine, then it spikes to 4500 and sits there.

Previously I've taken out the cluster, opened it up, nice and clean and dry, no rust, good solder. Have swapped in a friends cluster before the car was parked and the same issue happened with his cluster.
I have a spare ECM and the same issue remains.

Thoughts? Specific sensor somewhere? Wiring issue somewhere?

Don't have a lot of $ to professionally have it looked into, so cheap is what I'm looking for if you are willing to have a look or make suggestions.

Thanks so much for all your help. If I forget anything about the car, I'll update the post.

My gas gauge was sticky for a few weeks until I went through a few tanks. Of fuel.
I'd look into the tach signal/wiring/connection, I think it comes off of the ignition coil on G60's

The gas level sensor could be bad, pretty common. Measure resistance and the tank plugs. Can also test the gauge by connecting the two level sensor wires together. Gauge should either peg full or empty.

Rev gauge could a loose connection of the red/black wire on the ignition coil, or another wire in between the coil and cluster.

Thanks for the quick reply's.
Ordered the Gas Sensor from VM as there are only 2 left and discontinued.

I'm more concerned with the Gas sensor issue than the rev's, but will look into the wiring when I'm swapping the Gas Sensor.

Will keep you posted.

Thanks again!

When you get the new sensor, don't install it just connect the wires. With the key on, the gauge should vary with float movement.

Sooo NOT the Fuel Pump.
Car got to VM today to grab complete pump assembly.... It didn't make it home.
Have to say that BCAA PLUS is amazing service when they know you are blocking traffic. Took about 20 minutes for them to get to me.

So got home, RE & RE's the pumps. New pump turns on with ignition, Engine turns over but doesn't catch.

Thoughts?

I have no real testing tools to speak of and am most likely taking it to Euro Wrench Works in MR as they are 2 minutes away.
If interested in lending a hand, I'll buy lunch!

HUUUGE thanks for Dallas who was able to diagnose it as a bad ECU Relay - No spark.
Replaced the ECU and fuel pump relays (just to be safe) and it fired up perfectly.
Put in some new gas and all good. Actually runs smoother with the new fuel pump and relays - at least it feels like it.

FYI, THIS Corrado does NOT have a 70L take as the books say they all do!
Had about 3L in it, then was only able to fill it to 40L.
Kristian at VM suspect only a 55L tank.

This Corrado has a few things different than all others. As it was originally purchased in Germany, it seems to be a weird hybrid animal.
Never a dull moment!

Thanks again to Dallas and everyone from the community for helping out!
