S1 non runner - advice please

[muley]

S1 – non-runner now. After a run at the weekend I noticed a smell coming from the passenger footwell. Today I removed the carpet from under the dash and found the fuse / relay assembly (actually it fell to the floor). The fan relay had a melted terminal and the related fuse had melted away. I discovered where the short was, and re-arranged the wires and the car started OK. Then I taped up the assembly and put it back under the dash. Now the engine will fire, then cut out immediately. Questions are; could it be a faulty pink engine sensor? (This may have got hot as it was next to the fan relay) and what is the part number / source for the relay?

Any other ideas?

Had similar problems back in February. Suggest you check out 'Fuel Pump Help' thread from Feb 23rd it may be of some help. I got my replacements from David Gerald but I'm informed it's a standard Ford part from that era. Hope that's of use - let me know if you need more.
Best of luck.

I agree. The part is from a 2.8 Capri... There is a ford number on it that can be used to track one down. Also check the wiring from the ignition module under the bonnet. This can get water logged in between the wing and cause intermittent problems as well although melting fuses and relays is probably the first place to start.

Thanks for the feedback guys, and for finding the old thread...


I'll try to get a new relay tomorrow and let you know how I get on.

Well, I got the relay from my local factors, but still have the same problem. I'll start checking the wiring now. (Sigh)

After all that, it WAS the main loom connector( the crappy red and yellow one). Cleaned connector, rewired chunks of the fuse panel area and now all OK.

On to the next problem...

I am currently experiencing similar symptoms, however my fault is intermittent. Here’s what I have checked up to now.
1. Pink fuel pump module replaced (TVR main dealer was less than half the price of the local Ford main dealer!!
2. Checked all the connections under the bonnet for water ingress or corrosion. The bullet connections to the light blue ballast resistor were fairly badly corroded. I cleaned them but the problem persisted. The ballast resistor is a light blue coil of wire on the near side of the engine bay, close to the exhaust manifold. Disconnecting the resistor does replicate the problem (during the spell of happy running).
3. Cleaned and re-connected the main earth (close to the ballast resistor). This gets dirty due to exposure from road muck.
4. I then followed the wiring loom associated with the ignition circuit, to find that the tacho wiring is part of this circuit. I disconnected the three pin plug and socket to the tacho to check for voltage during an attempted start. When I re-connected the plug and socket I heard a click followed by the buzz of the fuel pump starting. I tried the key again and success the engine started. I have not had time to bottom the exact cause but at least I have tracked the problem to the loom in the tacho area of the car. Perhaps the problem is a bad connection or water ingress.

Hope this helps someone.
