If everything else is ok? The computer has to have the cam and crank signal or it won't start.
Any applicable trouble codes? Some makes and models, you can get some codes by cycling the ignition switch. You turn the key just till the dash lites come on, no further. You cycle the key, on--off, on--off, on, then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
