bit of a long story, after finally getting the gear box sorted was parking the car and it started to run very bad and then cut out. would not restart evntually ran battery flat. got the car home and started the diagnosis. hav checked all the obsivous areas, have fuel,spark checked compression,stripped timing belt covers all ok, replaced crank position sensor and tried a different cam position sensor still would not start, removed alarm incase was gone dodgy,still no joy. have tried a tow start also. when cranking it is poping out the exaust but no fire like the fuel is igniting in the exhaust. i have a simteck ecu fitted that im waiting on software from the uk to arrive so i can read the ecu. anybody have any experance of simteck ecu giving problems.i have nearly run out of ideas at this stage and head is wrecked
