i have a 93 toyota pickup 5spd 2wd with a 22-re engine. everything is stock in engine. just got flowmasters. anyway. sometimes my truck won't start..and sometimes it does start. i recentley changed my fuel filter and my air filter from the air box. my truck only has about 33000 miles. any advice on the problem..?.

You might want to check the starter or your grounds and every thing i had the same problem with mine

I know it is after the fact, but does it crank and not start or does the starter just click when you turn the key?
