Ford Zetec Non-Start Help Required

[japn]

Hi again Guys I have a odd problem i need your help with. am currently working on a 03/96 Ford escort 1.6 Zetec (L1E engine code) came to an abrupt stop on road, when attempting to start tries to run on what sounds like two cylinders then stops shortly after letting go of key 5-10 seconds, here is what I have done so far:

Checked cam timing & replaced timing belt all ok

Checked fault codes in ecu found coolant temp and air flow sensor stored ( not worried about these as should not cause a non start and fan runs all the time so reckon fan switch duff anyhow

replaced from donor vehicle:
cam sensor
crank sensor
Coil Pack & Leads
small box behind coil, looks like a surpressor or capacitor

ignition lock was really work co ripped out lock and now just running key directly to switch with pats immo areial around key dont think is immobilizer as without pats arial does not crank.

Just in case was cambelt I checked compressions 8bar on all four cyclinders,

Ford known problem of blocked exhaust so removed exhaust downpipe still non-start

I can here the fuel pump run on ignition and removed fuel filter while pumping to see fuel being pumped also clamped return fuel pipe incase fuel pressure fault ( unfortunately no fuel pressure gauge available)

I really do not know where I am going wrong but plugs dont look too bad or wet as if fuel problem. reckon is electrical.

has anyone had experience of this problem that could help. this one is cracking me up. unfortunatly I was working on my own so could not crank and test sprak ect on my own.

Any help appreciated.:motz:

Ignore what i said just looked at a drawing, first step is to check pulses to coil on pin 1 green/red, pin 3 green yellow both should pulse an earth i use what i call a mac light for this it has an led in it, when red it live when green its earth. Dont use normal test light will damage ecu. pin 2 on coil is black and that should be live on crank m8.

have you got a spark on all 4 plugs???

obd master I have a test probe I chall use this when I can, as currently I am on my own so unable to crank engine & carry out this test as of now but I am confident that it is firing on at least two cylinders but should I only find a switching feed on one of the two wires what would this mean would this mean that I have an ecu fault. what is the difference between these two wires does one do cylinders 1 & 4 and other do 3 & 4. would you have a wiring diagram for this system

You mean Mac ET-120 mine was ?28.80 in 1996 (http://www.mactools.com/Product/tabid/120/productid/318798/variantid/309557/Default.aspx)

Just jook for a little black box that is screwed to the inner wing think it might say 'edis iv' Ignition module

or

just change the fuel filter whilst thinking 'stupid place to put a fuel filter' whilst petrol is running down your arm.

You are correct m8, if you only find a switching earth on one of the two wires in pin 1&3 at coil pack, this either means your ecu is bad or you have broken wire. Then let me know and i will tell you which pin to test at ECU m8. The ecu is located left hand side kick panel m8.

Thats originally what i thought about ignition module (edis m8) but according to autodata ignition pulse comes straight from ecu on a 1996?

are any of the fuel injection relays worth checking and where are they.

and while we are on the subject if ecu is faulty where does the immobilizer system leave me. is the immobilizer code stored in the ecu or else where looks like the only vehicle key left working is worn out so no point re-building ignition lock without having key code. I have a autocom pro but on this model does not give the option of comms with immobilizer. what is the best program to recode keys on fords. or erase key code from immo ecu

Just check pulses as described then we will go from there m8

think maybe the autodata wiring diagrams are not reliable, Ive had problems with citroen wiring before I just looked up the diagram on my autodata system. not sure it the datalink connector is showing correct info as I have a full 16pin d connector but this wiring diagram seems to show 3 pin triangular connector that gives flash codes.

ok mate will let you know in the next couple of days

The story so far, well it seems OBDMASTER was spot on upon checking coil pack connector positive ign on centre terminal and switching earth from ECU on one terminal but last terminal had non-switching earth, sourced advice from local ford dealer, it turns out that a slightly faulty coil pack can blow the transistors in the ecu so advised to replace coil pack & ecu.

I had a donor ecu from another vehicle so swopped ecu together with ign barrel & Key to get around immobilizer problem did not swop coil pack as was already from donor vehicle now running on three cylinders. traced missfire to cylinder 4 swopped plug from 4-3 but miss still on cylinder 4 so swopped coil pack back over & hey presto all running fine.
the only prob I have now is that I was advised that scince the donor vehicle was fitted with air-con but the repaired vehicle not I may have probs in the future as fan speed charactaristics may differ. but so far so good.

One odd thing I did notice that is a bit odd is each ecu seems to be labeled different even though the part number is the same. for example one is called 'TUNA' & the other called 'STAG' does anyone know why, are there differences, should I need another ecu in the future what should I look for...

Glad its sorted m8, dont forget to hit the red thanks tab on the bottom right of my posts m8:driver:

No problem m8,
