followed write up from this site on cleaning MAF and changing spark plugs on 02 4runner. only thing i did different is when cleaning MAF i did not remove relay only unhooked negative battery cable. hooked everything back up, as soon as i put neg terminal back on hazard and dash backlight started flashing. no turn over nothing. CEL does not blink. Lights will blink for a short time then stop, when i turn the key to start the CEL comes on with the other dash lights. am i not resetting the computer right or what?
