aeromotive fuel pump and cranking power ?

Mustang_289 · 09-17-2006, 06:42 AM

We found yesterday it's not the aeromotive, we turned off the fuel pump from the inertia switch and the car doesn't crank over fast enough.

Everything was fine prior to the following work a few months ago - aeromotive eliminator fuel system install, Vortec T-Trim, Tremec TKO with upgraded guts, Stage 3 clutch.

Trans in nuetral drive shaft spins freely, clutch pedal in, drive shaft spins freely, removed the T-trim drive belt, no real change in the cranking.

What have you checked this far? Is this with a freshly charged battery?

The battery is freshly charged, we even put a new battery in and jumped it with an F250 truck with dual batteries.

This problem may be in the ignition, as my son pulled the plug off the MSD distributor and it cranked fine, put the plug back in and it struggles to crank. During the supercharger upgrade, we did add an MSD 6ALD box.
