Quick back story.....1957 210 Sedan, ground up garage restoration by me, FI 350 TBI, 200R4 trans, 3.73 Explorer posi traction rear, EZ wiring 21 circuit harness, Autometer gauges and a bunch of custom stuff.
Problem that I thought I fixed:
1957 Chevy ignition switch drops power from ign when turned to start which causes ECM to loose power. Power is need to ECM and fuel pump relay to tell ECM to fire.
My previous solution:
Installed relay - constant power to relay, feed output power to ECM, relay activated by key switch.
Result:
relay fried (after a couple years trying to find the problem). Must have burnt the contacts up because when switch was in run power was backfeeding into relay. Now post 87 (power output) is not showing power during start. ECM is not getting power during cranking because the key switch on a 57 does what it does. For some reason AWW (I think) rebuilt the 55-56 switches so they supply power in both run and start but didn't do the 57's.
Solutions (aka ideas):
Option 1
What is I relayed the key switch? If I install a relay so as when in start mode I feed power back to the run mode.
Option 2:
Install a RFI keyless start kit. I could drop $400 on a kit that just detects when I'm getting close, unlocks my doors, disables the alarm and powers the push button start. Then just hop in and push the start button. Sounds like fun. Might try to just relay the thing till I get the 79 Camaro done.
Question:
Will using a relay to power Run while in start be a problem?
