Tahoe Cranks But Won't Start
All,
Tahoe cranks and acts like some firing but no start.
Checked:
PMD: new backup plugged in: no joy.
Fuel Pressure: Plenty of fuel pressure with boost pump out the top of the Racor and the drain in startup sequence.
Relay: Verified all relays in relay box seated properly.
IP is new in last 20K miles from GM.
NO CODES
It has been really cold and the truck was hard to crank when it was down around 15F even with block heater. Thought it was the cold.
I put in anti-gel in the Tahoe and Sub before the blast hit early last week. Suburban has been starting and is starting fine.
I installed a Heath Max E Tork Saturday before last along with Turbo Master. After installed Tahoe started right up.
I got out Heath's manual and even followed the procedure to reset the timing.
Cranks but no start.
Any thoughts.
Thanks
