Right so some of you may already know i have fitted a puma 1.7 engine to my MK4 fiesta but i decided to remove the engine and clean it up (JET IT OFF) and now after re assembling i have serious problem, it initially started and ran like a jem for about 10 seconds then it cut out, and now after stripping down the inlet and exhaust manifold it keeps firing out of the inlet manifold, i have not messed at all with the timing so im very confused as to what it could be, i had it OBD checked and nothing came up, any ideas?

 

Put the ht leads back on the coil pack in the correct place?

 

Yeah triple checked, its firing no problem just at the wrong time,

 

Have you checked the timing.

 

I guess you have checked you have all sensors are plugged in correctly and not mixed any up?
I cant really remember the sensor layout of my old puma tho to suggest any that could possibly happen to.

 

Well i didnt mess with it at all so i dont see how it could have changed, if theres no easy fix ill take the motor out tomorrow and pick a new one up

 

Disconnect as many plugs as you can and check for water. Water around the spark plugs too.

 

Well i think im just guna drop the block out and tripple check everything, (might sound silly) but is there a sensor or sumit that controls the ignition spark?

 

Has water go into the engine??

 

Nope made sure the cylinders were empty and dry, flushed old oil and crap out the block using diesel and some other cleaner stuff, as i said it ran for a brief moment....

 

Firing at the wrong time sounds like ht leads on the wrong plugs as said above. Other than that there's nothing that could make it fire out of the inlet, as the vale would be closed.

 

This is exactly what i thought but i have had them off and changed them over cleaned them, there 100% on the correct way, Googled it and the corresponding numbers on the leads match up,

 

Well the leads must be faulty then

 

Possibly but they were fine before i took them off, they have not been anywhere near water, will replace them tomorrow anyway

 

If it's firing out of the inlet it can only be timing surely? Is the crank pulley on properly?

 

The only sensors i can think of that would effect timing are the crank and cam position sensors.
And having the ht leads on the correct way on the coil pack, and on the correct plug.

 

Its defo a strange one this. It just seems wierd since you steam cleaned the engine off its stopped working.

 

Well after alot of fannying around i have just gone backwards I managed to drop a 6mm nut into the cylinder and i cant get it out with a magnet, so i ended up punching something, Broke my finger (not my smartest moment) so i just cut my losses and went home, tomorrow im just guna strip her down to the shell and do everything properly and take my time, so ill be getting a new car for the time being......

 

You dont really wanna be doing that is there no other way around getting it out

 

Fpr has had it by the sound of it.

had the same issue changed fpr and job done.

 

Fpr?, i have bought another motor, and im going to replace the cams, need a little advice, is it literally a fact of taking the old ones out and put the new ones in?

 

Fuel pressure regulator..

 

Ohhh, bought a new motor any way.... any help on the cams, putting new up rated ones in?

 

What about the racing puma cams.

 

With the FRP cams is it just a simple swap over?

 

Up to a point. The exhaust cam needs to be retarded for 4 degrees IIRC and you need a special tool for that

 

Right im gong to do the timing and chuck the motor back together today and fire her up, Ill be doing a how to video on timing because there is lack of video help out there for it, ill post it here first to mak sure im correct

i also have a puma shell here that i have some what stripped, ill post photos, any one need anything off it?
