2005 FORD ESCAPE 3.0L ECM 5L8A-12A650
I need to replace transistors ,Ignition coil drivers
can someone provide me with info
what kind of transistors do I need to buy,
I can not read from my old ones

I bought BTS2140 from ebay and they are to big
cant fit to the board
where can i buy proper size ?

Are you planning to repair a bunch of these PCMs? With the time and effort involved in swapping those transistors, you're better of just swapping for a good used PCM. And fix the issue that initially caused the transistors to fail which is the spark plugs. I replace all 6 coils/plugs (Motorcraft only) since the upper manifold is coming off anyway.

its almost impossible to get good used PCM

What country are you located in? I've done well over 20 of these, all with used. Any local dismantler should have these by the boatload.

Back to this car again
found proper transistors 5503GM
and proper Current Sense Resistors
replaced them ,all coils and spark plugs new
vehicle start fine and after few seconds it badly misfires, i opened PCM
transistor for coil 4 burned again and one of the resistors also blown .
replaced them again switched coil and spark plug from cyl 4 to 6 start the vehicle
runs fine for few seconds and again misfire and same transistor for number 4 and one Current Sense Resistors blown.Any solution to my problem ?

Check for continuity/resistance on wires running from PCM to coil #4, also short to ground & short to power. Check for solid ground on motor. Perhaps something else is messed up inside PCM if those things check out?
