Ok so i have a 93 Sentra E as a daily driver back and forth to work. About a week ago i went to start it and it ran for about a second then died. it sounded like it wasnt getting fuel but i herad the fuel pump and it smelled like it was flooded. i am getting fuel to the injectors and i checked the signal going to them with a Noid Light in acordiance with the chilton manual all four passed. Next i checked spark, i pulled out each plug wire and had someone crank the engine while i watched them ark to ground. again all worked. so i checked the TPS sensor with a meter and it was fine. so i replaced the engine temparture sensor and still nothing. I then got to the ECM and checked to see if it threw a code and got code 55 which according to the book means nothing is wrong. I seem to be getting fuel air and spark but it just wont turn over. I searched but cant seem to find any thing on this. I dont know what else to change/replace and i need HELP. If anyone can give me some more infor or direct me to a thread i may have overlooked please let me know. thanks ahead of time for any info.
