This is a write-up by Mike_C Injectors not firing Is the tach moving too - just "having spark" isn't enough. If the tach is wiggling though then the signal wire from the ignition coil to the ECU & tach is working. Without that wire the ECU won't command fuel. It wants to verify ignition is present before it will flow fuel - this is a safety thing in case the car was in a wreck... don't want fuel being sprayed when the fuel lines, injectors, etc. could be busted wide open. To command the injectors, the ECU: * needs to see the signal from the ignition coil "-" post; this is the tach signal I just described. * wants to see pulses from the airflow sensor. The airflow sensor (aka "MAS" or "AFS") is the single most important input to the ECU for the fuel calculations; all of the other engine sensors just add or subtract from the AFS based value. * ECI fusible link must be intact. This powers the fuel pump, injectors, etc. * ECI relay (actually 2 relays in one housing) powers the fuel system and fuel pump. The ECU "holds" the fuel pump side ON as long as the ECU sees those ignition pulses ("engine is still running, go ahead and send power to the fuel pump..."); the ignition key START position also trips this relay to power the pump while you're trying to start. Some simple tests: 1: verify the tachometer wiggles. If not, find out what's wrong with the ignition system or your wiring. The wire from the coil "-" post to the tach and ECU is a skinny coax cable (skinny cable TV wire: a wire inside a braided shield, then encased in rubber) and it's possible for the inner conductor to short out to the shield if the wire is pinched, crushed, or bent tightly. Often it gets shorted right at the ECU connector. There are TWO of these shielded coax wires at the ECU - one is for the ignition, one is for the oxygen sensor. If you hook up an air/fuel guage to the wrong one you could screw things up. 2: Look for basic power to the injector while cranking: using a voltmeter red/positive lead probe either injector wire on the primary injector (the one closer to the fender on 87-later cars, or just pick either injector on earlier cars) and ground the voltmeter's black/negative lead. Now try starting... you should see 10 to 12 volts. No? Try the other post on that injector. Still no 12 volts? Then your ECI fusible link is shot, the ECI relay isn't ON, wiring is bad, or the ballast resistor is shot. The ballast is the silver prism-shaped thing bolted to the bulkhead between the air filter and passenger side headlight. +12volts goes in one wire, the resistor is actually two resistors that split this +12volt line... each resistor feeds one injector. Bad resistor = no power to injector. 3: Hook a noid light to the primary injector - the one closer to the driver side fender. It should pulse/blink if the ECU is completing the ground to fire the injector. mike c.

Your old account is still here. I can combine the two if you want me to. Welcome back. Jimmy -
Wow! This place is a ghost town these days!

It is owned by Bob Price aka Ryddler and always has been. Jimmy -
With this version of the site you can drag and drop pictures without hosting them anywhere. I drag them from my desktop. Jimmy

I sent Ryddler a message and asked him to update the home screen. Jimmy

I'd run it by Ryddler before changing it. Hit Bob up and I'm sure he will be willling to do it. Jimmy

Randy, You can just drag your pictures over. Jimmy

Freebird it is great to hear what you've done to his car. Jimmy

Caliber308 aka Bill Courtney has passed away and his wife, Gwen, is selling his car. Asking price is $10,000 which in my opinion is a great price. You can contact her at 406-696-9218 if you have any questions. Car is located in Arizona. Jimmy

Cal308 passed away in October 2022 in his sleep. He was very knowledgeable about Starquests and will be missed. May he Rest in Peace. His wife, Gwen, wants to sell his car. I posted it up in the Cars For Sale Forum. Jimmy
