hello
i have come across an 2002 altima 2.5S very nice car, it will start and run for about 3-4 seconds and turn off. the scanner at first stated that the code p1612 p1610. after trying to check out the fuses and relay i can not get it to say and codes. it has been wrecked into a guard rail but had been driven for about a month after. I wonder if that antitheft relay could be at fault? but not sure where it is to find out. will be replacing the cam and crank sensors as soon as money is in hand. if it is the keys saying its wrong would it even start and run? or just crank over?

thanks

ok update, replaced the ckp and it runs, ran about 20-25 minutes turned off and now the same thing, will be trying another brand of ckp
