Brief summary: This study will provide information on the use of insulin lispro and insulin aspart in insulin pumps in participants with type 2 diabetes.

Detailed description: This study will provide clinical information on the use of insulin lispro in continuous subcutaneous insulin infusion (CSII) in participants with type 2 diabetes. This study is designed to allow comparison of the 2 rapid-acting insulin analogs, with regard to their efficacy and safety, when used as a pump insulin therapy in this participant population. Each participant will be randomized to 1 of the 2 sequence groups in a 1:1 ratio and randomization will be stratified according to screening A1C (less than or equal to 8.0% or greater than 8.0%) and thiazolidinedione (TZD) use (yes or no). The study design includes the following periods: Screening/Randomization, Treatment Period 1 (16 weeks), and Treatment Period 2 (16 weeks).

Eligibility criteria: Inclusion Criteria:

* Have type 2 diabetes (per World Health Organization \[WHO\] Classification of Diabetes)
* Have been treated with CSII therapy using a rapid-acting analog for the previous 6 months
* Have a screening A1C less than or equal to 9.0% (no lower limit for A1C)
* Have a body mass index (BMI) less than 45 kilograms/square meter (kg/m²) at screening
* Have a history of stable body weight (not varying by greater than 10% for at least 3 months prior to screening)
* For participants on oral anti-diabetes medications (OAMs): must have been on a stable dose of OAMs, labeled for use with insulin, for at least 3 months prior to study entry

Exclusion Criteria:

* Have severe insulin resistance \[require greater than 2 units/kilogram/day (U/kg/day) of insulin\]
* Are taking or have taken within the last 3 months, antihyperglycemic medication not approved for use with insulin, injectable non-insulin antihyperglycemic medications, or have a contraindication to current antihyperglycemic medication
* Have a serum creatinine greater than or equal to 2 milligrams/deciliter (mg/dL) if not on metformin; known metabolic or lactic acidosis; any condition associated with hypoperfusion, hypoxemia, dehydration, or sepsis; and/or a radiologic contrast study within 48 hours prior to study entry
* Are receiving chronic (lasting longer than 2 weeks) systemic glucocorticoid therapy (excluding topical, intraocular, intraarticular, and inhaled preparations) or have received such therapy within 2 weeks immediately before screening
* Have had more than 1 episode of hypoglycemia (defined as requiring assistance of a third party due to disabling hypoglycemia) within 6 months prior to entry into the study
