    88383convertable , Today 02:10 PM
    88 TPI convertable cranks no start without spraying fuel into throttlebody and won't pulse injectors
    noid light confirmed no injector pulse
    40lb at fuel rail
    ​​​new coolant temp sensor
    new pick up coil
    TPS .54
    VATS module bypass
    new 02 sensor
    new ignition control module
    new coil,cap,rotor,plugs,wires
    new ECM new fuel pump relay and MAF relays. Car ran rich when it ran last week and developed a starting issue leading to intermittent starts and long cranking time to start when cold. After driving and engine warmed up the car started first try. After chasing these demons and replacing seemingly everything but the injectors the car now won't start only fired on the cold start injector then dies.Please help I love my car and don't want to ditch the TPI for a carb.
