I wonder if anyone can help, I have a 1993, L reg ford escort 1.4 single
point injection escort.
The problem is that I have starting problems, the car does start most of the
time but sometimes
it just turns over and wont fire, sometimes it does this from cold but also
if I have took it for a run, the problem is intermittant,
I havent got the money for expensive diagnostics so was wondering if anyone
thanks in advance
Sadly, I'm not familiar wih the British Escort.... I must assume that the
electronics are similar to North American vehicles, though..... On that note
(and taking into account BYMs suggestion about state of tune), realizing we
have no codes or other data to work with, let's look at those things that
can cause a no start (other than ignition related components)... The TPS
could be intermittent - if the PCM sees a high throttle opening during
cranking, it assumes that the motor is flooded and reduces injector pulse
width - denying the motor of the fuel needed to start. When the key is first
turned on, the PCM takes a quick peak at barometric pressure... if the MAF
or MAP has an intermittent fault, it can tell the PCM that local air
pressure is different from reality. This will affect fuel mixture and can
either starve the engine or overfuel it. There may be a concern with the
electric fuel pump or it's circuitry. Any other number of concerns can give
Not to preach, but "expensive" diagnostics are generally cheaper than
throwing part after part at a concern. I can't recount the number of times
I've fixed a simple concern that some well meaning DIYer has thrown hundreds
and hundreds of dollars worth of parts at...
