1997 Ford Ranger engine turns over and has spark, but wont

I had to replace the head of my 97 ford ramger 2.3 super 8. I also had to replace the timing belt, spark plugs. I have it all back together and the engine turns over, but will not start. I have pulled the middle plug on the passenger side, grounded it to the engine and had my son turn it over. Got a good spark, a little white, but good. I pulled the spark plug to see if i coud smell gas, faint smell of gas was the result. Alll vaccumm hoses are in place except the ones coming from the coil packs. I also checked the gas filter on the frame from the tank to the filter no problem, from the filter to the zirt on the fuel injectoion main tube, no problems. ???? help
