i just picked up a salvage elise and have been trying to get it to start in the few weeks i’ve had it while i gather the parts to fix it.
the car didn’t come with a FOB only the key for the ignition so i started out with bypassing the immobilizer which got it to crank but the fuel pump still didn’t kick on. The inertia switch was also triggered but after hitting the switch still no fuel.
i got it to start and run on starter fluid so i know that it’s forsure a fuel issue. checked all fuses as well and none are blown.

i have a new fob on the way and i’m getting the PIN code to sync it as well but i don’t get why it wouldn’t start if the immobilizer was the problem since it should be bypassed. the only thing i can think is that maybe the inertia switch is somehow bad or i have a bad pump/ relay? car only has 40k miles so pump would be my last guess. any insight on something like this? some of the wiring to the rear lights is a little tore up but i don’t see how that would effect the fuel pump wiring.

When I turn mine on and deactivate the immobilizer, I immediately can hear the fuel pump kick on for a few seconds until the pressure comes up (from sitting in the drivers seat). If you can’t hear the pump come on, then that’s the issue. Either your bypass didn’t activate the pump circuit or something else in the pump circuit is dead. Do you have a wiring diagram?

yeah definitely no fuel pump noise. i just spliced the fuel pump wires together that are in the immobilizer plug like everyone else does. i’ll try to find a diagram and mess with it tomorrow.

I might suspect the fuel pump relay. I think it’s on the firewall right in front of the engine. Possibly in a row of 2 or 3 relays.

finally got this figured out. one of the gator clamps that was supposed to be jumping the fuel pump wiring wasn’t cutting into the wiring enough. what threw me off is all
the DIYs online state the skinnier wires i had tapped correctly were the fuel pump when it was actually the starter wires. took the clamps off and actually cut the wires and used a but connector and it fires right up.

i started on the front and have been taking pictures of the body work, i might start a thread once i’m done and post all the pictures. i’m getting rid of the front signals, all reflectors, and the seams front and back.

If you blend the seams, won’t that make it difficult or impossible to remove the clams? The front needs to come off from time to time to service various components.
