Stuck!! No crank ! LF some input and help !

Much appreciated but I think you are right about shipping costing a little much !!

Great thank you ! I went to Partssource today and they only had 40amp relays. Looks like I'll need to order some which works because no one carries 3/8 female ends either. There is one store I maybe able to get it all from I will try and go tomorrow (where I got resistors from)

When I did my relay mod I put a fuse in series with the relay contactor and did a little experiment. 5a fuse blew, 10a did not blow, so I put a 15a fuse in. So this means that you are probably safe with the 40a relay at least in a pinch until you can get the 80a. I have been running with the 15a fuse and a Hella 50a relay for a few months.

Good to know thank you for the input ! I can at least get started soldering some wires and use this one in the meantime.

I read Marc's website about narrowing down the no start. I went into the car with my multimeter and just checked one of the relays which I believe to be the starter relay (has both thick purple and yellow wires going to it)

Key not in. No power to yellow. Key all the way forward (crank) and I see 12 volts on my multi meter. The purple however .. Is getting no power. Again.. No expert with nearly no experience with relays but does this mean it's narrowed down to the trigger wire on the relay? I'll have to dig my service manuals up and figure out where the wires come from but they are yellow and a yellow with a black stripe . I took a photo and marked them. Based on the relay diagram when energiZed the yellow (30) should connect to the purple(87) and voltage but I am getting none.

I would think that START ENABLE RELAY needs to be treated differently depending upon the year that has the NO CRANK - the CRANK circuit I believe is only "similar" in operation but wired very differently in the later years. OP yours is I believe a later '94 but I don't ever see you mention it.

I'll update the original thread it is a 94. Sometimes I think all years are the same but you're right .. Over the last few days I've read about changes from 90 and vats changes in 93+ and the starter relay as well. I guess I'm just thinking out loud but hopefully I'll be able to post up a definite solution .

You are correct there Dave....I did NOT install the Clutch Bypass Relay (the Relay that sends direct current from the Battery to the Starter Motor) on my 95'......I just restored/installed a new starter among other things

It is obvious from this first photo that this is a 94' or 95' from the ASR (under the red milk shake) and single Throttle Cable among other things



It also appears there exists an Oil Catch Can from the plumbing related to the PCV valves.
On the 95' I installed my oil catch can under the Drivers Side Head Light as normally I would install the Oil Catch Can on 90' or 91' where the ASR is shown above on this 94'-95'.

Not really '92+ has ASR so... BUT '93+ has the somewhat different STARTER ENABLE I believe.

Last night I looked again and i see that the clutch switch is wired with 2 thin wires vs what some threads and others posted about finding thicker wires. I believe this is what was changed to remove the current going through the switch in 93+ years.

I'm busy with the kids all day but hoping to get time to get a relay and I'll be free tonight to wire up the relay.. I hope ! Hopefully I can figure out which box I have my service manuals in and I can try and understand the wiring diagram better in hopes to at least pinpoint what was at fault in my situation.

There's your problem in the top picture...
The milkshake appears to be vanilla, the schematic in the FSM clearly
calls out for chocolate... 😄

Lol! Been so exhausted the last several days/week moving ..I felt I deserved an iced cappuccino from Tim Hortons

Well good news is I went to the electronics store .. They had everything but 60/80amp relays. I picked up connectors 1/4" and 3/8", ring terminals , new soldering iron (long overdue I've been using a torch but don't want to be using that near the car or other wires), a fuse wire (30a fuse rated for 40) and some other stuff. I just hope I get time tonight to get it done.
