Hi my 1991 caravan with 3.3 liter engine died while driviing down the road at 50 miles an hour ,and would not restart ,so i had it towed to my house ,my neigbor which was a mechanic for many years came over and tested it with his computer reader but it showed no fault codes,but the check engine light blinks 13 times when you check it.Anyway we have been trying to solve this problem for aweek now both he and i are stumpt here is a list of what we have tried ,we first replaced the fuel pump ,that dident fix the problem it still had no spark so ,we replaced the ecm next to the battery that did not fix it either ,then we replaced the camshaft sensor ,that dident fix it either ,checked the auto shut of relay its fine , so the computer is shutting down it will not let the car start it keeps sending a signial to the auto shutoff relay and it will not let it spark at this point i dont no what else to do i can keep replacing sensors but dont no if thats the problem why wont this computer let my car start!!!!!! any suggetions anyone oh ya the reader said the map sensor was at 19 and had 5 volts of power .

Well i was ready to throw in the towel but i thought id try one more thing since eveything seemed to point that way i replaced the crankshaft sensor on the trany crossed my fingers and it started right up well i must say what a releaf that it did i must say it runs better now then it ever has and my gas guage works again since i replaced the fuel pump too so if anyone has these sympotoms and no codes when you check the computer i would recommend try replacing crank sensor first.
