1993 Range Rover Classic that wont fire up

[rangie]

i have replaced the heater matrix on the car, i took it for a drive and the heater was working fine, after 10 miles the hazards came on and the engine was reving up and down in time with the hazard lights, i switched it off and it would not fire up again, now everytime i try to start it up it doesnt start and the hazards come on. I have had an auto spark have a look and he suggested the ecu alarm, i replaced this and the problem is still there. I have not replaced the 2 relays that work in conjunction with the alarm as i dont want to waste any more money for the problem to still be there. Can you help?

It sounds like you have bought a clown's car, when you pull up do all the doors fall off?

last thing you need when you have a problem some smart arsed remark.

however have you tried the engine control relay
positive should be term 86
negative should be term 85
there should be a resistance between these of approx
50 ohm
teminals 30 & 87 should be open circuit
if a supply is put across 85 & 86. then 30 & 87 should be short circuit
