I have a 1994 Vauxhall Frontera 2.0i petrol and I have been fleeced many times trying to sort its fuel problem. The trouble is that it refuses to fire up when I start it and a mechanic tells me it is the fuel pump at fault. Having been told this, the fuel pump has been replaced but the engine still won’t start. I have already paid for the work and have lost all my money on this car. What’s wrong with it?
The mechanic says...
First try going back to the mechanic who told you it was the fuel pump, and establish from him/her why they felt the fuel pump was at fault.
A commonly encountered problem with the fuel system on Fronteras is failure of the fuel system relay (located behind the left side headlamp panel) or its fuse; check these aspects or have them checked. Ensure too that the fuel pump filter is okay.
If the relay and/or fuse seem to be the culprits, yet the engine won’t run after these have been renewed, it may be necessary to renew the whole relay plug/socket assembly. Ensure that all the fuel pump wiring is sound too, including the earth connections.
In order to get a precise diagnosis of the cause of the problem, it would be worth getting an auto-electrician to check the entire system, so that any weaknesses in the wiring and/or components can be identified and the problem(s) rectified.
