Default Sierra 2.0i EFI wont start

Hi!
The problem is s the title says. The car is model a year 1991 2.0i OHC (PINTO) engine with EEC IV EFI with HEGO (lambda) and catalytic converter (witch BTW was removed by the previous owner). The car runs on petrol and LPG. Before the problem the car had some hesitation when accelerating while driving on petrol and on LPG was running fine.

Yesterday I was fitting a new rear exhaust silencer. After I welded the silencer I turned the engine on to check if the weld was good. The engine did run fine. After that I lowered the car and removed the jack stand. Tried to start the engine again and now the engine cranks but wont start either using petrol or LPG

I checked the ignition by pulling a spark plug wire off of a spark plug and placed the open end of the plug wire near a metal surface on the engine. My m8 cranked the engine while I watched for a spark and there was sparks.

When the LPG system is switched to petrol and I turn the ignition key I hear the pump working and when I switch to LPG mode I hear the LPG solenoid open.

My guess is that the compression is OK as the timing belt is in place.

Any suggestions on what could be wrong?

As I understand the collision switch cuts off the fuel pump. And my fuel pump is working when I turn the ignition key. And also the car has the LPG that is not affected by the collision switch.

Maybe the pump has crud inside preventing fuel to flow enough or maybe a fuel filter ?

Default Sapphire 2.0 pinto

I bought a Ford Sapphire 2.0 Pinto 2 weeks ago. Car starts fine sometimes on the 1st swing,can drive to the shop and come home. If i swith the car off and try to start again it just cranks. Sometimes it will crank a few times and then just nothing like the battery is dead.. i changed the earth wire. Made a new connection to the body old wire was bit corroded.
If i leave the xar standing for a bit it starts again no problem. Does anybody know what i can try? I am really not very clued up on cars and know zero about engines.
