So i recently bought a 94 Mustang GT 5 speed, has some mild upgrades like intake, headers,exhaust, msd ignition. It will start up good almost all of the time, but the last few mornings that ive been driving it to work, it will crank for a few minutes before it finally catches and starts running. I can smell fuel and i always get it to turn on, it just depends on how long i feel like sitting there and cranking the engine. It did this once and night and sometimes will crank for a few seconds and then turn on but usually it starts up pretty good, but this few minutes of cranking every morning is starting to suck. I live in mass and i feel like this is related to the colder mornings we've been having. Thanks in advance guys.
