1990 Geo Tracker

Have a 90-Geo.......replaced motor, would start an run spraying starter fluid for a few seconds! Traced it to a bad fuel pump,replaced it with a new one, Now its not getting fire to plugs an fuel pump won't kick on! Is there a reset button on this model, that will kill fire to the ignition an pump for safety reasons? Thanks for any help!!

I think the engine has to register oil pressure before the fuel pump will kick on.
(not 100% on this but check to make sure the wire is connected to the oil sensor on the drivers side of the engine. ) worth a shot. otherwise check all your grounds.

The oil pressure isn't monitored by the ECU. The ECU is the common factor that controls the fuel pump and ignition. Have you checked the fuses?

No fire to Coil or fuel pump!

I have checked all the fuses that I can find, there are 3 big ones right in front of battery an of course the fuse block under the dash, are there any more that I may have missed? Thanks Larry

The ECU is up under the dash. I believe its on the passenger side on LHD models. Have you got a Check engine Light warning? It might be worth disconnecting the fuel pump again in case there is a short in the wiring. It has been known for problems to develop with the connectors behind the rear light cluster, I can't remember which side it is though.

One prob. solved/another to go!

The no fire to coil an pump was finally found in a blown fuse! After tearing the dash apart an tracing the hot wire al the way back to the pump.....the new pump we recieved was wired backwards!!! Using the factory connecters, which snaped right together, it was sending the hot from the fuse block to the ground on the pump which of course -blown fuse!! Was a easy fix but hard find!!Thanks for all the help guys! This is a 90-Tracker, we put a 95 motor in it,we had to use the old dist., but trying to use new intake an carb. which had a few extra plug-ins which we don't have. It cranks an runs but is running way to rich, could the computer set up not be suititable with this intake an carb from the newer year? Should we change back to the original intake an carb. ? Thanks for any suggestions............Larry

Hi Larry
You mean a 1990 throttle body, right?. Here in the UK we had carbs on our Zuks up to around 1994. From what I have read over the years 1990 was a changeover year for EFI on Track/Kicks. The 1989/90 models had a slightly different EFI set up with a different TPS and possibly a few other differences too. As I understand it the 89/90 ECU is not compatible with the later system. You will need to determine what setup you have, the 89 TPS is just a 2 switch set up for for idle and WOT, the later models have a variable resistor.
Cheers
James
