Hi guysI apologise in advance for the long winded please help post, but am out of ideas with this.I recently acquired an 88 fxgt corolla with a bigport tvis 4age engine.It had been overheated, with a suspected blown headgasket.Could still turn crank over with socket on the pulley.I replaced the rubbish radiator and re filled coolant...went to change spark plugs and noticed water in top of #2 and 3 pistons.So head came off, gasket hadn't blown between 2 and 3 but head was bent.Had it shaved flat, new bolts and head gasket - reassembled and tried it...cranks continuously but wont fire. Since then I've tried and checked the following:Cam and crank timing marks checkedNew distributor rotor, cap, plugs, wires and ht lead plus a different distributorSparks on all 4 leads with spark plug outTested coil and ignitor all okFuel pump runs when jumped at diagnostic and cor relayWon't start with engine start in intake or individual cylindersEng main relay was missing when got it but replaced Ecu board looks gd no leaking capsTPS tested okOnly thing I can find that may be odd is with the IGN on and while trying to start, all injector pins are showing 12v. Not sure what may cause this.Also after cranking with new plugs in afterwards they don't appear to have had any combustion near them but not sure if this is lack of spark in the cylinder or lack of fuel due to an injector issueCould something with tvis be a problem?Any other checks I could make or any ideas why she won't catch please let me know...it's doing my head in now!Cheers
